One of the most important questions is How do the fitness trackers, clip-ons, activity bands and other fitness wearables work? How do they count the steps and how do they track the quality of sleep. Let discuss this in details.
Fitness Trackers are all about Sensors
Fitness trackers are nothing but the pack of different sensors to do their job. Different fitness trackers use the different number of sensors to track the activity accurately. While most of the fitness trackers have three to four sensors, Microsoft Band comes 10 sensors as advertised by the company. The latest models of different fitness trackers offer different functionalities thus the number of sensors varies as well.
Most of the fitness trackers have these main sensors.
- Optical Heart Rate Monitors
- Bio-impedance sensors
- Ambient light Sensors
- Galvanic Skin Response Sensor
- UV Sensors
1. Accelerometers track your movement
Accelerometers are part of almost all the fitness trackers and use to track the motion. If you were wondering about how do the fitness trackers count steps? The simple answer is with Accelerometers.
The Accelerometers measure the acceleration in different coordinates depending on the type of Accelerometer. If the accelerometer used in the tracker is two-axis, they will be less accurate as compared to the three-axis accelerometers. Along with Accelerometers, gyroscope and altimeters also help to measure the altitude, orientation, and rotation to accurately count the steps in different conditions like when climbing mountains or while walking in a park.
This data is converted into steps and then on the basis of steps count, calories are calculated. You can understand there is some sort of guess work involved in this whole process.
Ever Wondered Why Different Fitness Trackers Come With Different Results?
Every fitness tracker processes the data using its own algorithm.
Let's take the example of Step counting. When counting the steps, one fitness tracker can ignore a slight movement whereas another fitness tracker can consider it as one step. The Threshold for defining the step varies from brand to brand thus the accuracy varies as well.
For Example: 0.25 miles are 540 steps for a Jawbone UP, 538 steps for FitBit One and 552 steps for Nike Fuelband.
2. Optical Heart Rate Monitors measure your heart rate
The Optical Heart Rate Monitors use the light to measure your heart rate. All the fitness bands which support heart rate monitoring have an optical heart rate monitor on their back which intact with your skin to measure the pulse rate. The LED shines a light on your wrist and illuminates the capillaries which help sensors to measure the blood pumping rate which in turns tells us the heart rate.
The optical heart rate monitors are less accurate than the Bio-Impedance sensors but help us getting the heart rate especially when doing an exercise or work out.
3. Bio-Impedance Sensors measure your heart rate in more complex but accurate way and help in tracking sleep quality as well.
Some of the fitness bands and trackers use the Bio-Impedance sensors instead of heart rate monitors to measure the heart rate. Jawbone UP3 is one of them. The Bio-Impedance sensors measure heart rate, galvanic skin response, and the respiration rate and are more accurate than the normal optical heart rate monitors. The Jawbone UP3 according to the official post uses the impedance changes created by the volume of blood flowing in the Radial and Ulnar arteries.
These Bio-Impedance sensors not only measure the heart rate sensors but also tell existing respiration and hydration conditions by measuring the oxygen level in the blood. To this, it uses the four electrodes which inter-transmit an electrical impulse for the purpose.
4. GPS are a must have in your fitness tracker if you are a professional runner
As we discussed above, the Accelerometers are used to measure your step count but the bands with GPS sensors are more accurate and provide better results. The GPS technology uses the low-power, high-frequency radio signals from different satellites orbiting around our globe. This mechanism calculates the precise distance by getting the data of your starting and ending coordinates.
Unfortunately, the GPS sensors drain the battery too quickly but still with the improvement in technology, more and more fitness trackers are offering the built-in GPS.
5. Ambient light Sensors track the sleep quality by combining different factors
The fitness trackers with a display screen use the ambient light sensors to maintain the screen readability in different light conditions. They work same like they work in our phones for managing the screen brightness. The Ambient light sensors are also used to check the darkness in your room.
The ambient light sensors only detect the light which is visible to the human eye for this purpose, which is then sent to the processor after converting into a digital signal to measure the sleep quality and other factors.
The other sensors included in different fitness trackers are thermometers to check your body temperature; UV sensors are used to detect other light wave and their impact on your body and the Galvanic Skin Response sensors which are used to detect any change in your skin like sweat while doing exercise.
How Does Fitness Trackers Track Your Sleep
Fitness trackers and activity bands use the accelerometer to measure the sleep quality. Most of the fitness trackers have the 'Sleep Mode' which tells the tracker when enabled, that the person is now sleeping.
Measuring sleep quality is a complicated process and not all the fitness trackers are best at it. To check the sleep quality, there are a number of lab tests used for the purpose which measures brain activity, eye movement, heart rate, muscle tension, oxygen level and breathing as well.
Some of the fitness trackers claim to measure the different states of sleep like Deep Sleep and light sleep. They use heart rate monitor, body temperature, and pulse oximetry along with accelerometers for this purpose and give more accurate results as compared to normal fitness trackers.
How the Data is Processed
If you have used a fitness band earlier or if you have read anything about them, you will be aware of the fact that different fitness trackers give different results in same conditions. Many bloggers did the tests by wearing the multiple trackers at the same time and they got the different results.
The Data Accuracy of the fitness trackers depends on the two factors.
- Number and quality of Sensors Being used in the fitness tracker you are using AND
- Algorithm which is used to process the raw data into information.
We have discussed the different Sensors and their usage in measuring the activities above. Now we will look at the algorithms used to process data.
Once the band or tracker you are using has collected your activity data, it now starts processing it to give you results. Every brand uses its own algorithm to process the data and bring the results in front of you. Because the way of processing data is different for every brand and usually brands do not share their algorithms, it is the main reason; we see different results on different fitness trackers.
Let's take the example of Step counting. When counting the steps, one fitness tracker can ignore a slight movement whereas other fitness trackers can consider it as one step. The Threshold for defining the step varies from brand to brand thus the accuracy varies as well.
Similarly, when it comes to talking about calories, different trackers ask for more details from the person using the tracker. Like, Your Age, Gender, height and weight all matter in this regards along with the steps count for calculating the calories burned. Along with steps count, your heart rate and the perspiration rate also matter.
The more accurately the algorithm takes all this information and processes it, more accurate the results of fitness tracker are. Some companies like MotionX have spent more than $50 million to design more advanced and accurate algorithms. According to the estimates, existing trackers and bands can show different results with 20% average deviation.
With more and more choices to choose from, it has become more complicated to choose best fitness tracker for your needs. Earlier most of the fitness trackers only used to count steps and sleep monitoring. Whereas for running and other activities there were other watches but with the advancements in technology, more and more fitness trackers are offering a lot of features in one band.
You can now count your steps and measure the calories burnt along with sleep monitoring and heart rate monitoring. You can use the same tracker for swimming and other hyper activities like climbing and running with most of the modern fitness bands available in the market.
One of the other most important factors in this regards is the App to use with the fitness tracker. As we discussed above, every fitness tracker has its own algorithm, similarly, every brand has its own app and most of the brands support the third party featured rich apps as well.
Fitness Trackers Are Best For General Use!
If you are a professional athlete like runner or swimmer and thinking of buying a fitness tracker or a fitness band to get a detailed breakdown of your activities, you will be disappointed.
While Fitness trackers can give you detailed information about your activities they are still not best to use for measuring the advanced metrics required for different sports.
Key Factors To Find The Best Fitness Tracker For Your Needs:
1) Ask Yourself the Question. Why Do You need a fitness tracker or band?
Before you go and buy a fitness tracker, you should completely understand your own requirements. Why do you need one is an important question to ask yourself. More you are clear about your requirements, more easily you will be able to select the best fitness tracker for yourself.
Angela McIntyre, the research director at Gartner, sums it very beautifully:
"Fitness trackers are motivational to people for getting more exercise and living a healthier lifestyle. If there is a particular activity you like, like swimming, make sure the activity tracker and the software are designed for it. People who have a favorite activity that is less common, such as jumping rope, may want to check that the activity is recognized by the software."
So if you are just starting and planning on adding some dedicated time for regular exercise in your routine, a basic tracker which can count steps and measure calories burnt is the good starting point for you. But if you are already spending a good time in exercise and workouts of different nature, you should go for more advanced trackers to fulfill your needs.

2) What Type Do You Prefer? Wristband Vs Clip-on
Fitness trackers are available in different sizes, styles and shapes. It depends on you how you prefer to wear it. Depending on the choice, if you feel comfortable wearing it on your hand you can go for a wristband. But if you don’t find it convenient for yourself to wear the band all day or all night you can prefer a clip-on which you can clip to your belt, clothes or shoes.
It completely depends on you to choose between the two options. Most of the modern trackers come with a screen to show you your activity at runtime. So it is important for you to wear your tracker in a way you can easily note the readings when required.
3) What Features Do You Need?
Once you have clearly understood your needs, you can easily decide which features you will be needing in the fitness tracker which is the best fit for you. Almost all the fitness trackers come with built-in features for step count and measuring calories burnt. Sleep monitoring and distance calculation are also now standard features of fitness bands.
a) Water resistant fitness trackers will help you take a shower and swim without taking it off.
If you have involved in water related activities, you should prefer the waterproof fitness trackers. You should know the difference between the waterproof and splash-proof trackers. While waterproof fitness trackers work fine if you take a shower or you do swimming, splash-proof trackers will only save it from light water contact like sweat.
While waterproof fitness trackers work fine in water and will give you some readings of your swimming activity, not all waterproof trackers will give you accurate results. So if you are looking for a fitness tracker for your swimming needs, you should make sure to read the specifications of the band first.
b) Heart Rate Monitoring is critical especially if you are 35+.
Optical heart rate monitors are becoming more and more common among the fitness trackers. With the advancements in technology, these optical heart rate monitors track the heart rate with a lot of accuracies. For instance, the optical rate monitoring technology used in the Apple Watch gives results as accurate as of the ECG. But again not all sensors are made equal.
Most of the fitness trackers, having optical heart rate monitors, become useless with a little contact with water or sweat on the skin. So if you are looking for a tracker for your swimming activities, the old chest-strap heart rate monitors are still your best choice, which uses the electrical impulses to measure your heart rate.
c) GPS is a must have for runners but it eats battery very fast.
If you are a runner, cyclist or a hiker, you should prefer the fitness tracker with built-in GPS. While there are a lot of GPS smartwatch available in the market, most of them lack the heart rate monitoring and other key features of the fitness trackers which can be really handy for you.
The GPS-enabled devices to pinpoint your exact location, measure your speed and tell more accurate results as compared to the accelerometers. On the other hand, because GPS uses the satellites for communication, it can be slow responding some conditions and can drain the battery of your tracker more quickly.
d) With Screen or Without Screen
There are fitness trackers in the market with screen and without the screen. It is completely your choice i.e. what do you prefer. Most of the fitness trackers which have screens show some very basic information like steps count and time etc. Still you will be relying on your smartphone and the app for detailed information and data analysis.
e) Long Battery Life means you can collect more data without breaks
If you have used the feature phones, you know how poor the smartphones in the battery area are. Same is the problem with smart watches and fitness trackers. Most of the smartwatches need to be charged at the end of the day which means you need to take it off. On the other hand, most fitness trackers have a battery life of at least 7 to 8 days which means they can keep tracking your activity 24/7 and give you more accurate results.
f) Silent Alarms with vibration only wake you Up!
Some of the fitness trackers and clip-ons offer the alarm feature. This can be very handy in cases when you share your bed with your spouse but you don't share the wake-up time with him/her. In such cases, your wristband starts vibrating and only you wake up instead of your whole family.
g) Sleep Tracking can help you work on your sleep disorders.
We have discussed earlier how the fitness trackers track your sleep. Although many modern trackers use different algorithms to track your sleep, they are still mostly dependent on your movements in sleep. But If you are working on sleep disorders, you should choose the fitness trackers which not only use the accelerometers for sleep tracking but also use the optical heart rate monitor to check other important factors like oxygen level.
4) Data Syncing And Compatibility
The fitness trackers track your activity, collect the data and then send this data to your smartphone. That is why it is important to make sure that the fitness tracker, you are going to buy, is compatible with your phone or not. Most of the trackers work fine with iOS and Android OS but many of them do not work with the Windows Phone.
Similarly, some fitness trackers transmit data automatically to the phone once paired whereas some require pairing again and again. You should choose the tracker with these things in your mind as well.
5) Companion App is Feature Rich or Not
The most important part of the data has been collected is to analyze and present it. This job is done by the companion apps for fitness trackers which are installed on your Smartphone. You should take care of several things before choosing the brand from the app perspective. The companion app should display details clearly, should be simple in design and should allow you to sync with other third party apps like MyFitnessPal. Similarly, the sharing feature of the apps is also very important to share, compare and compete with your friends and family. This plays a vital role in motivating you.
Most of the fitness apps also allow you to lodge details like food intake and other nutritional details. Similarly, some apps let you distinguish between the workouts to calculate the data more accurately.
One of the main factors to focus from the app perspective is different features on different apps for iOS and Android. Like there are more features on the iOS app of a brand as compared to Android, which is frustrating. If downloading and using the app without the tracker is difficult, you can still go to Apple AppStore and Android Play Store to read reviews and comments about the app.
Talking, in general, every fitness tracker has its own features and lacking. That is why it is most important to understand your needs and then decide the device accordingly.
6) Check the Strap or Band Size
Most of the fitness trackers and bands come in the different strap (band) sizes so one can adjust the band or tracker to his/her wrist perfectly. It is important for the wrist tracker to be in contact with your wrist all the time especially if your tracker comes with heart rate monitor.
Almost all the good brands provide the sizing guides so you can find the right size for you by measuring your wrist circumference. Like you can check Microsoft Band 2 Sizing guide, Fitbit Charge HR sizing guide and Garmin Vivosmart HR sizing guide on the respective links.
Remember, each model of the same brand can have different size requirements like Microsoft Band and Microsoft Band 2 have different sizing requirements.
So, you have either bought a fitness tracker that fits your needs or you have decided the best one for you. Great Job!
But Hye...! It's still the 'Job half done'!
As we discussed in the beginning, only 1 out of 10 people uses the fitness trackers on the regular basis after some period.
Why is that So?
1) Human nature of ditching 'old things' which were quite appealing some days ago?
2) No Motivation? Lack of Goals, or losing the faith after expecting a lot from yourself and the fitness tracker you have.
The most important thing is to use your fitness tracker on the regular basis and get the most of it. And we will be discussing in the next lines how you can use your fitness tracker effectively.
Be Realistic - Fitness Tracker will not do the magic for you:
Like any other tool or device, fitness tracker does nothing itself. It will never do a magic to make you fit but it is you who can bring the change by using the tracker properly and regularly. That is why it is most important set some realistic expectations from your tracker. As we have already discussed, fitness trackers are still not accurate, so it can be a frustrating factor but on the other hand, fitness bands can be the biggest motivation you have.
This is same like you buy a trade mill to lose weight and stay active, but unless you use it properly, you are not going to get anything from it. So the most important factor is to bring change in yourself and stay focused and consistent.
Wear it Always to get more accurate results:
Although this is certain that you will be wearing your band most of the time but it is very important to wear it always, no matter what you are doing. Definitely, your tracker will never count the steps if you have taken it off your wrist and this will result in false results at the end of the day.
That is why it is very important to buy a fitness tracker which is comfortable for you and its size is according to your needs. Most of the modern fitness bands and activity trackers are designed considering this that you will be wearing them 24/7.
Similarly, taking your tracker off your wrist can result in forgetting to wear it again for a certain period of time. Suppose you put your tracker on charging and go for a bath and then you go to office forgetting your tracker at all. Now coming back and picking the tracker is not something you will be willing to do but this will result in wrong numbers and you will start finding it troublesome when analyzing the data.
So it is very important to wear your tracker always and whenever you take it off put it near to other important stuff like your Car Keys and your phone.
Set The Small Targets and Goals which are achievable:
This happens with every one of us and always. We are pumped and start doing workouts and exercise without a proper plan. And after some time, all our motivation fades away and we are back to our routine.
But fitness trackers can help us in this regards. Being more active a day is easier said than done because the standard step goal is 10,000 steps in almost all the trackers but we take only 5000 or fewer steps per day. If you think, you will double your steps in a day or two, it is unrealistic. Instead, you should try to achieve this ultimate goal of taking 10000 steps on the daily basis gradually.
First, you should start observing your daily habits by wearing the band for a day or two, then you should find the ways when you can walk more like using stairs instead of an elevator, parking your car away from your office and going on foot for shopping in the neighborhood instead of using the car. This will help you achieve your targets and goals in the whole day instead of doing the whole activity or workout in given period of time.
Similarly, do some research by reading about fitness levels for different people of different ages, gender, and weight! Find what is appropriate for you, then break this ultimate goal into further small goals and try achieving them in a month or two.
This slow and steady approach will help you change your old habits a lot.
Go Social and Connect With Others:
You can start with a lot of enthusiasm and energy for a week or a month after you buy your fitness tracker. But soon you will get tired of the routine and you will need some motivation to carry on. This is where you need your friends or family members to join you. Ask your close friend or a family member to start participating with you using the tracker and you will find the differences.
You both can set daily challenges to compete and use it as a motivation to remain active for a longer period of time. You can also join social communities and find the people like you and start competing with them to achieve your goals.
Keep Logging Details in the App on Daily Basis:
We do different types of activities on daily basis. Going to a washroom, crossing the road and taking a long walk in the park for an hour or so are all different activities which need a different amount of energy. The fitness trackers will count them all as steps and you will have to keep your activity data more up to date by inputting different information. You can use third party apps like MyFitnessPal and MapMyFitness to get an accurate picture of your steps at the end of the day.
Similarly, the fitness tracker will keep the log of how many calories you are burning but what about the calories you are taking? You should start logging your food intake details in the app as well to get the complete picture and analyze the data in a correct way.
Do Fitness trackers worth? In Short, Yes! With reasonable expectations, you can take a lot of advantage from the fitness trackers.
The advancements in the latest technologies and the growing use of smartphones will eventually lead to the more robust, featured rich and accurate activity and fitness trackers. Similarly, we will be seeing the growth in the usage of fitness trackers with technology advancements.
Right now, we can see there is very less difference between a fitness tracker, GPS running watch, and a smart watch. Most of the fitness trackers are now offering all these features. Although the technology is used today is still not accurate but still, the fitness trackers are one of the most important motivational tools to keep you on track and have a check on your daily activities.
Depending on your requirements, if you only need to get information or a more accurate advice than just a simple guess work, fitness trackers are best fit for you. On the other hand, if you are professional athletes and your requirements are more complicated, you should go for the dedicated watches or straps available in the market.
You can also use your Smartphone for getting details of your daily activities. The Apple Health App and Google Fit on Android do the very sophisticated job and give you very detailed results in this regards. Or you can prefer a smart watch if you want the features of your phone on your wrist. But what makes fitness trackers more appropriate is their battery life which is normally of 5 to 7 days as compared to 18 to 20 hours battery life of smart watches.
In the end, what is most important is to stay active and keep a check on your health and fitness to improve your quality of life. And fitness trackers can be a useful motivation tool for you to keep running walking or doing what you like the most.
