How Do Fitness Trackers Measure Steps

How Do Fitness Trackers Track Steps

Over the past couple of years, fitness trackers have become admired and used by a lot of consumers. 

While the tracker resting quietly on your wrist, it is measuring your steps, heart rate, how many calories you have burned, and even, your sleeping pattern. 

When you first use any fitness tracker you input your physiological details like your gender, weight, and height so that the tracker can better analyze the data it collects. 

Nowadays new tracker models are being produced with improved features meanwhile the price keep falling which is leaving the customer wondering how accurate these calculations are. 

In this article, we are going to discuss with you how do fitness trackers measure your steps, so stick around….

1. The Sensors

Your fitness tracker has a sensor in the form of a 3- axis accelerometer that can detect your motions. 

This allows it to track movements in all directions; it can tell you are walking, running, or even standing still.

It also includes a gyroscope that allows it to measure rotation and orientation. 

Many trackers are provided with an altimeter that makes it capable of measuring the number of stairs you climb every day or the height of the mountain you hike on your trip.

2. Processing

All the data collected by your tracker are stored and furthered processed when transferred to the software that is associated with the fitness tracker when they are synced whether it’s on your smartphone or your PC.

The software already has your personal data, and it uses the information collected from your tracker to understand what the different motions imply you were doing. 

3. The Algorithm 

Each manufacturer had its own algorithms; those aren’t really available for anyone to check.  

These algorithms help your software to categorize your movements and group them into different activities that you can check later under different headings on the application associated with the tracker. 

You need to understand that what makes the readings of one tracker different from the other are those personalized algorithms. 

It’s true that a tracker might miss a small movement and not count a step or two and that is something that is still unavoidable no matter how expensive or fancy your tracker is.

However, a lot of times your fitness tracker is not way off track, the numbers you get are more or less accurate. In my humble opinion, it’s better to have an estimate than to have nothing. 

4. The Application

This is the final stop and is focused on representing your processed data. 

As mentioned before, each tracker is connected to an application and you can find a variety of information available on this app. 

A lot of the apps come with an option to add data and exercise manually. 

Once your data go through the algorithms, they are refined and presented in a better format that is more user-friendly.


Fitness trackers can measure your steps by an amalgamation of sensors and algorithms that are able to count your every step and display this data later on an app that is connected to the tracker which makes it easy to keep track of your movements and exercises.

How To Choose A Fitness Tracker

How to choose a fitness tracker

If you’re looking to buy a fitness tracker, you’ve probably searched and have been overwhelmed with the number of choices available.

Even though Fitbit tends to dominate the topic, there are many other options that shouldn’t be overlooked.

And in any case, you should know how and what to look for when you’re shopping for a fitness tracker.

If you don’t, this guide will walk you through it all and help you form a better idea about which device would suit you best.

All-day or training tacker?

Trackers are generally divided into two types. There are ones that only track training-related information including heart rate, breathing patterns, speed, pace, route, swimming laps, altitude changes, and sometimes they have music control.

On the other hand, there are ones that track all-day activity including steps taken, steps climbed, exercise duration, minutes spent active, and sleep tracking.

Design and Style

The wrist-based bracelet-like fitness trackers are the ones that prevail in the market.

However, you’re not restricted to them. You can find trackers in the shape of a necklace, a ring, or a tracker that you can simply clip on to your clothes.

If you like matching your wearables to the clothes you’re wearing, you can make use of trackers that can be customized and that come with interchangeable bands.

Moreover, since you’ll be wearing your fitness tracker 24/7, you should make sure that it feels nice and comfortable on your wrist. It should fit you really well as you’ll be making vigorous movements during exercise.

To make sure you get the perfect fit, measure your wrist with a thread and match it to the lengths available for the model you want to buy.


Although you may think the display is a minor part of the fitness tracker, it actually plays a major role in the functionality of the device.

There are a couple of features that you should pay attention to when you're picking a fitness tracker including whether it has a touchscreen, side buttons, color or black and white display, visibility in different light conditions, and size.

Make sure you get a device with an intuitive interface to maximize your utility and enjoy all the features. The worst thing in the world is paying good money for a device that irritates you when you’re navigating through it.


Popular features on fitness trackers include general activity tracking, sleep tracking, and heart rate monitoring.

Of course, these things can either make or break the value of the device. So it’s crucial that you identify the functions that you want out of your fitness tracker before you buy one.

Data and metrics play an important role in your journey towards improving your health, losing weight, or training and losing weight uniformly.

Moreover, feedback and motivation can really help you stay on track and achieve your goals on a daily basis as well push yourself beyond your limits.

Activity Tracking

Without a doubt, activity tracking is the most important aspect of a fitness tracker.

The very basic is step-counting, but you can definitely ask for so much more.

There are activity trackers that have multi-sport tracking to cover different activities and you should know a few things.

If you're looking to track your steps taken, distance, running, walking, or cycling, you'll need GPS for accurate results.

Since not all fitness trackers count the floors you’ve climbed throughout the day, you should make sure you get one that does if this is important to you.

The calories burned count will only be a close estimation based on steps and movement if your tracker doesn’t come with heart rate monitoring.

No matter how accurate tracking is, there will still be some wrong calculations. For example, you’ll probably burn more calories running on the beach than running on the road.

However, for your tracker, your calories burned will be the same as long as the distance covered is the same.

Sleep Tracking

Sleep tracking is mostly based on readings of the heart monitoring sensor.

If sleep-tracking is important to you, make sure you get a fitness tracker with accurate heart monitoring.

Moreover, do your research well that the sleep-tracking statistics are accurate as the degree of accuracy varies from one device to another.

Generally, being aware of your sleep patterns can really affect your overall health.

However, you shouldn’t rely on the information provided by a fitness tracker if you’re suffering from a sleep disorder. Consulting a doctor would be the wisest choice.


One of the most useful features for runners, cyclists, and hikers is GPS. It allows you to track your routes, discover new ones, and get advanced data about your activity.

Typically, there are two kinds of GPS options for fitness trackers.

Built-in GPS: 

This is where the device is readily equipped with GPS.

Linked GPS: 

This is where the device pairs with your smartphone to extract GPS data.

Of course, built-in GPS is a lot more helpful as it spares you the need to take your phone out with you whenever you do exercise outdoors.

However, a tracker with built-in GPS will probably cost a lot more than one with linked GPS or none. On top of that, it'll probably have much shorter battery life.

Heart Rate Monitoring

Most of the recently-released fitness trackers come with standard HR capabilities.

However, the degree of accuracy of the sensor and the data that you get from it can greatly vary.

How heart rate monitoring works is that optical sensors read the blood pulses in your veins. So the more advanced the sensor technology, the better the heart rate monitoring.

Some trackers step their game up a notch and determine VO2 Max (which determines the maximum amount of oxygen that you can burn during vigorous and intensive exercise), stress levels, cardio fitness score levels, and more.

Furthermore, some trackers come with a SpO2 sensor which detects the amount of oxygen present in your blood and thereby is able to determine how athletic you are.

These extra features are all great additions to a fitness tracker that focuses on your health and improvements to it.

Apps and Downloadables

Before you decide on a particular fitness tracker, you should make sure to inform yourself regarding the apps that are available for this device.

Which app you like is quite subjective, but if you read the user reviews before you make your purchase will probably help you make the best buy or avoid a useless one.

You can use different apps alongside the tracker’s app. So you should check for compatibility before you make your purchase.

Waterproof or Water-resistant?

It’s a fairly obvious point that if you’re buying your fitness tracker to track your swimming activities, you’ll need a waterproof one rather than one that just resists water.

In all cases, a fitness tracker is usually water-resistant up to a certain level rather than completely waterproof.

This level is measured in ATM ratings or meters. So you'll find "5 ATM" or "50 meters" in the information on your fitness tracker.

And although a tracker that can resist water up to 50 meters is generally safe to swim with, getting one with a 10 ATM rating would be better and allow you to swim rest assured that nothing will go wrong with the device.

To give you a better idea:

1 ATM (10 meters) will be splash and rain resistant. 3 ATM (30 meters) will also sustain a quick shower.

5 ATM (50 meters) will also handle accidental submersion or shallow swimming.

10 ATM (100 meters) is the best as you can go swimming without having to take it off or worrying about anything going wrong with it.

Battery and Charging

The battery life is usually closely linked to the features available on the fitness tracker.

A device with GPS capabilities will probably have shorter battery life and will need to charge more frequently.

While most trackers come with a 4 to 5-day battery life, you can find ones with CR2032 batteries that you’d only have to change every couple of months.

Charging time shouldn’t be overlooked. The shorter, the better. And it can compensate for a short-lived battery.


There are two types of notifications to be considered.

Smart notifications such as calls, texts, and apps on one hand and inactivity notifications or alarms on the other.

Since many devices mix between being a fitness tracker and a smartwatch, you can definitely find a device that will track your activity and still keep you connected to the world around you.

Moreover, inactivity reminders and silent alarms can be really helpful when it comes to sticking to your routines and achieving your activity goals.

These alarms can remind you to take medications, get moving, and drink more water.

Compatibility With Your Devices

A lot of fitness trackers will come compatibility with both iOS and Android operating systems such as the Fitbit devices and Garmin devices.

However, if your watch runs on iOS (like the Apple Watch Series), it’ll probably have more features available for smartphones that run on iOS (like the iPhone).

The same also applies if your watch runs on Android (like the Samsung Galaxy Watch) it’ll perform better with Samsung Phones.

5 Reasons You Should Buy a Smartwatch

A smartwatch is a wearable piece of technology that you can use for general purposes.

They’re usually capable of fitness tracking as well as keeping you connected through notifications and apps.

If you’re wondering why you should spend a good amount of money on a smartwatch just so you can do your timekeeping, we’ll have you know that the capabilities of a smartwatch go way beyond that, and here’s how:

5 Reasons You Need A Smartwatch

1. It Can Double As a Fitness Tracker

A smartwatch can really help you out when it comes to tracking your fitness and healthy lifestyle.

You can keep tabs on your heart rate –especially with a smartwatch that sends you alerts if it rises above or falls below a certain level that you specify.

Moreover, it can be your workout buddy or even your personal trainer with its activity reminders and the on-screen workouts you can access through downloadable health-related apps.

Not only that, but some smartwatches help you track your diet, weight, calorie intake, and distance you move (walk, jog, run, or cycle) throughout the day.

Finally, a smartwatch can have a sleep-tracking capability to help you form an idea regarding your sleeping habits and your sleep quality.

With all this information at your disposal, you can easily learn about the areas that you need to improve and what habits you should work on.

2. Keeping You Oriented

A number of new cars come equipped with dashboard Google or Apple Maps to keep you aware of where you are on the road and where you’re going –brilliant idea!

But what if you have an older car, a motorcycle, or a bicycle?

With a smartwatch, you can simply specify the location to which you’re heading and turn off your phone’s screen.

After that, a persistent notification card will appear on your smartwatch’s screen to let you know the distance before the next turn.

This is especially helpful if you’re on 2 wheels as they don’t give you as much space to check your map out as if you were in an enclosed vehicle.

3. Making Everyday Nuances a Thing of The Past

Do you often misplace your phone? Once you connect your smartwatch to your phone, you can easily use the very convenient “Find Phone” feature to ring it and instantaneously find it.

How about forgetting to lock your car? With the smartwatch connected to your car’s system, you can lock it from a pretty wide range’s distance.

The ultimate use is to connect your smartwatch to your smart devices. Then, you can do your laundry, prepare your meals and coffee, or even warm up your house before you arrive on a cold winter day.

4. Keeping You Connected

When your smartwatch is connected to your phone, all your notifications will be delivered to your wrist.

This means you don’t have to take your phone out every time you hear it ring.

Sometimes you’ll even get the option to answer or reject calls from your smartwatch. And if it has built-in speakers and a mic, you’ll be able to carry out the whole call without taking your phone out or carrying your phone with you.

A bonus to using your phone less frequently is that your phone’s battery will last longer with you.

Instead of relying solely on your phone and constantly draining its battery and recharging it –something that invariably leads to reducing the longevity of the battery, you can divide the effort on both devices.

Add to that, it spares you the hassle of having to change the battery of the watch itself because it doesn’t even have a battery.  You simply have to charge your smartwatch. And you don’t even have to do it that often as most smartwatches can last a minimum of 3-4 days on a single charge.

5. Customizable to Your Personal Taste

With a traditional watch, you don’t get that much customization options. I mean, they usually come with a standard strap, so matching your watch to your outfit would require you to own multiple watches.

However, a lot of smartwatches come with interchangeable straps to fit your outfit. Moreover, you get to change the face of the screen itself. You can set it as a picture you took, a downloadable wallpaper, or whatever matches your mood.

Final Thoughts

After mentioning all these things, it’s not that hard to see how a smartwatch beats a traditional one in every way.

However, you may be concerned with the price. But if you think about it, in the long run, you may spend the same amount of money on changing the batteries of all the watches you own.

And when you compare the price to the technology integrated to the smartwatch, it doesn’t seem like an unfair trade-off.

A smartwatch can make your life a lot easier and more convenient, even in ways, you wouldn’t have noticed before.

Just let it be known that to really make use of the smartwatch, you have to be a little tech-savvy and have to be a technological enthusiast. Mix that with the great features a smartwatch has to offer and you have a match made in heaven!

8 Reasons You Need A Fitness Tracker

Getting a fitness tracker is a very effective way to help you improve your health. With a variety of functions, your fitness tracker can tremendously help you get closer to the healthy lifestyle you aspire to reach.

What they do, basically, is they calculate your daily steps, count the number of calories you burn, monitor sleep patterns and eating habits.

By doing so, you’ll find it easier to make any changes to your life that lead to a healthier lifestyle.

1. Keep Tabs On Your Activity Levels

A fitness tracker is the most reliable method to record your activity levels and push you to reach the minimum 10,000 steps per day that an active lifestyle requires.

Moreover, by always checking how many steps you took, the distance you’ve walked, and time of activity you’ve spent, you will be better able to know if you need to move more or maintain your level.

2. Share Goals And Compete With Friends

With a fitness tracker, you can share your goals, progress, and statistics on social media or create a personal workout group where you and the members share competitive goals.

This works on two aspects of human nature:

  • When you voice your goals to someone, you’re more likely to follow through with the actions.
  • When you feel like you’re competing with someone, you’re more likely to put in more effort into your work.

3. Monitor Your Heart Rate

Monitoring your heart rate can be very useful when it comes to giving you an insight into how healthy you are and your overall fitness levels –especially resting heart rates.

Some smartwatches even come with sensors to determine blood pressure and the blood oxygen levels of users.

4. Keep Track Of Your Sleeping Patterns

Fitness trackers help you form a better idea regarding your sleeping patterns.

Sleep can have a great impact on your energy, mood, cravings, and metabolism.

Usually, you’d get information regarding the length and quality of your sleep, how deep you’ve slept, how many times you’ve woken up during the night, and how much time you spent in each sleep stage (REM, light, and deep).

If your sleep pattern is affecting your activity levels or overall health, a fitness tracker would be a choice to regulate it and make it healthier.

And generally, monitoring your sleep pattern can help you identify various sleep issues and get you on the road to fixing them.

5. Maintain A Healthier Diet And Achieve Weight Loss

The tracking of fitness trackers doesn’t just stop at activities. You can make progress with your diet by logging all the food you take.

With some trackers and apps, you can get a detailed calorie count with the number of calories you should consume within the day. Then, every time you eat something and log it, it reduces the number and displays how many you have left.

When you’re aware of what you eat and the calories associated with it, you’re motivated to say no to some things and moderate on others, therefore reaching a fitter version of yourself.

6. Build Habits For A Healthier Lifestyle

By monitoring all the aforementioned things, your fitness tracker will be able to recommend some manageable goals and easy-to-make changes that aim to help you develop healthier habits.

With its help, you can replace coffee breaks with refreshing walks and high-calorie foods with healthier ones.

Not only that but with the reminders on your fitness tracker, you’ll constantly be reminded to move and drink more water.

You can even make use of these reminders to either begin forming a healthy habit by reminding yourself to practice it (such as meditation) or to quit an unhealthy one by becoming more aware of how constantly you do it (such as smoking or biting your nails).

7. Holds You Responsible

Getting a report of your activity levels just to find them relatively low makes you feel responsible and encourages you to move more.

This is applicable to consuming unhealthy foods, not drinking enough water, or not keeping a consistent sleeping schedule.

More often than not, we tend to put a lot of things before our health and not give priority to it. That’s why fitness trackers hold you accountable for your actions and give you a clearer idea.

And they’re more reliable than your memory recall or your wishful thinking.

8. Having A Personal Trainer On Your Wrist

Your fitness tracker can give you a personalized workout routine and guide you on how to perform the moves properly with the correct technique in order to achieve the expected results.

If you don’t have the time or the money to go to the gym and pay for a personal trainer, you can pay once for a smartwatch and get a lifetime of personal training.

Usually, they provide you with a fitness routine that you can follow to spare you the research and the wondering.

Some of them even come with a wide range of trainer profiles in order for you to pick the workout intensity level that best suits you.

Moreover, it also shows you the statistics of the previous day and encourages you to outdo yourself.

Final Thoughts

A fitness tracker is seriously a one-way ticket to a healthier lifestyle.

From keeping track of your activity levels, heart rate, sleeping patterns, calorie-intake, and setting mini-goals, there isn’t an aspect of your life that you wouldn’t be working on and improving.

Moreover, it motivates you to change your unhealthy behaviors, holds you accountable, and encourages you to set, pursue, and achieve your fitness goals by keeping you are of your daily habits and tracking your progress.

It’s like having a personal assistant whose whole job is to help you reach the best, fittest version of yourself.

And with the various brands on the market, you wouldn’t have to worry about not finding one that doesn’t match your budget, doesn’t have the features you’re looking for, or doesn’t fit your style.

How to Pick The Right Fitness Tracker for Your Kid

How to choose a fitness tracker for kids

When choosing a fitness tracker that would suit the use of a child, you should keep in mind a few things that would facilitate their operation of the device. They would probably enjoy something that is interactive and integrates fun into its work. You’d also need a device that’s easily handled and taken care of, as well as being durable and light.

How to Pick a Fitness Tracker for Your Kid?


The display is very important for a child to pay attention to their fitness tracker and interact with it. The Apple Watch Series always have amazing displays with high resolutions and rings that indicate the progress of the user when it comes to moving, standing, and exercising.

They’re a great way to motivate your child to integrate all these actions into their day, and also challenge them to complete the ring on a daily basis.

As for Fitbit devices, the Versa would seem to have the most colorful and interactive screen, but its size might be a little too big for a child’s wrist. Your child could also make use of the attractive display on the new Samsung Galaxy Watch with its high resolution and its colorful screen.


A fitness tracker’s design will make a huge difference to your child. A lightweight, compact design is much preferred as it will be more convenient for them to go about their day with.

The Fitbit Ace does a great job when it comes to being a good fit for a child’s wrist, but it lacks the attractiveness of the display.

The new Apple Watch Series 4 also uses the System in Package technology in a very brilliant way to make the size of the watch very compact relative to what it has to offer. Although it could have too many features that a child might not make use of.

Battery life

The longer the battery life of the fitness tracker you get your child, the better it would be. Some fitness trackers boast a battery life that lasts up to 7 days like the Alta HR.

The Garmin Vivoactive 3 also lasts around 7 days on smartwatch mode (13 hours on GPS mode). One of the longest lasting batteries would be the Fitbit Zip that could function for up to 4 or 6 months.


At the sight of a pool or a sea, children might get too excited to remember to take off their fitness trackers, so it’s best if you get your child a fitness tracker with water-resistance.

Some good choices would be the Fitbit Flex 2, the Garmin Vivoactive 3, or the Apple Watch Series 3. The latter 2 also deliver swim-tracking and display swimming-related data such as types of strokes and distance.


Usually, a fitness tracker will promise to deliver you two major kinds of features: Fitness and smart features. A child would probably make more use of fitness features, that’s why it would make more sense to buy them a device that focuses more on those kinds of features like the Garmin Vivoactive 3 or basically any Fitbit device.

The Fitbit Ace has 2 Fitbit app views: one for the parent and one for the kid. This specific reason qualifies it to be the best candidate for a child’s fitness tracker.

How Do Fitness Trackers Track Sleep?

How Does Sleep Tracking On Fitness Trackers Work?The simple answer to this is comprised of two components: Heart rate monitoring and an accelerometer.

Heart rate monitoring is a vital feature that fitness trackers have and it tracks your heart rate throughout the day and during the various kinds of activities you do.

They can, with statistics, tell which of your heart rates indicate sleep, which indicate being still, which indicate mild activity, and which indicate vigorous activity. Using this information, a sleep tracker can tell when you’re asleep or not.

Some trackers even come with automatic sports recognition which can easily tell when you’re doing different activities like walking, running, cycling, dancing, playing sports, or swimming.

An accelerometer is a sensor that measures the acceleration of your moment throughout the day, to indicate different activity levels. They can also indicate the number of steps you took and even the steps you’ve climbed if the tracker has an altimeter.

Both of heart rate monitor and accelerometer combined together work to give you sleep monitoring that is as accurate as possible.

How does your fitness tracker know when you’re asleep?

A question that asks itself, however, is whether sleep tracking feature in those fitness trackers is reliable and how accurate the information is.

Well, for a regular everyday consumer, the answer would be that they give you a good idea and a general background on the quality of your sleep. Although it is not a hundred percent accurate.

However, if you’re a person with a medical condition or a sleep disorder, these fitness trackers may not be the most accurate devices to use. This applies especially to the tracking of sleep stages which is something some of the fitness trackers’ manufacturers claim that their trackers do.

To monitor the stages of your sleep, experts and professionals use brain waves and eye movements to give an accurate estimation of how much time you spend in each stage of sleep, broken down into light, deep, and REM sleep.

This is the most accurate way and anything else wouldn’t give you reliable information that you can use for treatment or improvement with your sleeping disorder.

Compared with the polysomnography –a scientific evaluation of a person’s sleep-, the fitness trackers were easy to trick due to their great dependence on the accelerometer.

How Does Sleep Tracking On Fitness Trackers Work? | Bottom Line

So the bottom line is, if you’re using the tracker to give you a general idea on the quality of your sleep, then there are no worries and you’ll get a good background on how well you sleep.

How Do Fitness Trackers Measure Calories Burned?

When purchasing a fitness tracker that has a calorie burned indicator feature, you must ask yourself how would a fitness tracker calculate the amount of burned calories? If we are going to be real, the thought of it being just a smartwatch wrapped around your hand must have occurred to you, how does it function?

How Your Fitness Tracker Tracks Calories Burn?

How Do Fitness Trackers Track Calories BurnedLet us start from general knowledge first, our BMR short for “basal metabolic rate” is simply the rate at which you burn calories while you are resting just to maintain vital body functions such as: breathing, heartbeat, and brain activity.

Usually your BMR is estimated for at least half of the calories you burn in a day and it can be accounted based on the physical data you entered when purchase a fitness tracker then start creating a health profile which includes information such as: gender, age, height, and weight.

Based on your BMR calories, fitness trackers calculate the burned calories based on your heart rate, it is most likely the best and most reliable way of calculating.

So let’s say If you were very stressed during that meeting, and your heart rate was elevated, the chances of your calories burning abilities will be much higher than usual.

Moreover, a fitness tracker provides an in-depth estimation by taking into account not only the BMR as mentioned above, but also adds on the activities recorded by your tracker, in addition to any activities you might log manually.

The longer you wear your tracker the more accurate your resting rate, and the more accurate your resting rate is, the more accurate the calorie burn estimation will be.

There was a study made a while ago done by some doctors along with an experiment that was based on people testing out fitness trackers by wearing them then later debate any conflictions made between the results of the fitness trackers as devices and the results the doctor produced using professional and medical devices; the study assured how fitness trackers have very low errors in their estimation and their accuracy level is good, and how usually the device work by using the BMR method.

The BMR count in your  fitness tracker will reset itself every night at midnight thus you will be able to start a new day with a fresh negative counter that will begin counting immediately even if you have just gotten out of bed, and it is all thanks to how BMR burned calories work.

Although we should note that any fitness tracker can very much count your heart rates precisely but you can not rely on it for how much calories are burned, after all each body’s metabolism works differently as well as the BMR, it differs from one body to another.

At the end of the day, fitness trackers can not be accounted or relied on for an accurate amount of how much your body has burned calories. It is always best to keep up with a professional rather than a device.

How Do Fitness Trackers Track Heart Rate?

How Does a Fitness Tracker Measure Your Heart Rate?Lately fitness trackers have invaded the sports world by a storm, it is quite rare now to find a fitness tracker that does not have a heart rate tracking feature. The big questions here are how does it do that? And how precise can it be?

Usually any fitness tracker can also measure your activities such as the distance you walk, the number of steps you climb and the calories you burn, that is why these trackers are becoming an essential device for athletes in order for them to keep tabs on their health stats.

Do Wearable Heart Trackers Actually Work?

These trackers can be placed on your wrist, they are adorned with sensors that can measure the acceleration, frequency, duration, intensity and patterns of your movement while you are exercising, one of the most important sensors of a tracker is the light sensor; these fitness trackers use light to measure the body’s pulse.

The process works by shining a light into the blood vessels located in your wrist after that they start to detect the changes in the blood volume which happens every time your heart beats and pushes blood throughout your body. Sensors on the device detect how much light your blood vessels reflect back thus less reflected light means a higher blood volume.

This technology is called photoplethysmography or PPG for short.

Furthermore, this technology is not only used in the tracker devices but is also used in hospitals. Experts confirm that the devices that use this technology are very accurate at monitoring the heart rate, in spite of that these devices verge to be a bit imprecise when a user starts making an intense activity.

How Accurate Are Fitness Tracker Heart Rate Monitors?

Long story short, these wearable technologies rely on using an LED light to make the capillary veins in your wrist visible to a sensor in order to measure how fast your blood is pumping, after that this information is then interpreted as your heart rate and later is presented in a “beats per minute” data format.

However, if you want to receive an accurate reading, the wearer should be totally still thus any simple move can effect the tracker’s heart rate reading.

If you want a device that solely works on getting an accurate heart rate reading, then a fitness tracker might not be your call.

We suggest getting a heart rate monitor watch, it requires you to be still so it could read your rate, and unlike most trackers; instead of taking an idle reading of your pulse, the device requires you to touch your finger to a built-in pad to such a degree the results have a more accurate reading, one that fitness trackers aspire to have.

The Battery Life of The Fitbit Versa – How Long Is The Fitbit Versa Last?

Fitbit Versa Battery LifeThe battery life of any device is the thing that determines how often you have to worry about recharging it, and for a Fitbit, recharging may seem like a tedious job as you have to keep taking it off and putting it back on.

At face value, picking a Fitbit with a good battery life may seem easy: just pick the one with the longest battery life. However, the battery life is affected by many things.

The longest battery life is on the Zip (lasting 4 to 6 months), but the Zip has little to no features other than counting steps.

There is the Alta HR that lasts up to 7 days, but its features aren’t extensive as other models down the line. A lot of the Fibit watches have battery lives of 5 days like the Flex 2, Ace, Alta and Charge 2.

However, their features don’t compete with the Versa, specially when you bear in mind the female health tracking that the Fitbit Versa is equipped with.

How Many Days Last The Fitbit Versa Battery?

The Fitbit Versa’s battery can last up to 4 days on a single charge.

Which isn’t too shabby when you think about the perks of the features it has to offer.

Think about the thorough heart rate monitoring it has to offer using PurePlus technology as well as FitStar workouts that make you feel like you have a personal trainer on your wrist.
