What is a Fitbit? Let’s Figure It Out.

You are probably wondering:

What is Fitbit?

So, if you are the owner of a new Fitbit or are planning to get your feet wet with the world of fitness tracking, you will find this review helpful. Fitbit like any brand of smartwatches is constantly evolving but has common key functions that are always transferred that make this range of devices a hit in this segment.

So, Fitbit is a complete usage guide.

What does Fitbit Do:

-Track steps (measured by hand)
-Sleep tracking (measured by hand movement)
-Calorie Burning Rating

And some trackers will offer even more:

Automatic activity tracking
-Pulse rate tracking (resting heart rate, real-time pulse rate)
-Advanced sleep tracking (using heart rate)
-GPS tracking workouts in the fresh air
-Connected GPS connection to use your phone’s GPS for outdoor training
-Notifications and alarms

Fitbit Pulsometer

Heart rate tracking is an important feature of modern fitness wrist devices, and most Fitbit models now have a built-in heart rate monitor.

Firstly, these are some of the Fitbit devices with a heart rate monitor:

  • Fitbit ionic
  • Fitbit Versa
  • Fitbit Versa lite
  • Fitbit Charge 3
  • Fitbit Inspire HR
  • Fitbit Alta HR

How does FITBIT Heart Rate Measurement Technology work?

Fitbit uses Pure Pulse’s technology to determine the amount of blood flowing through the wrist. These lights flash hundreds of times per second to get the most accurate BPM data (beats per minute) to determine how much green light is being absorbed.

Although every company working with this optical sensor technology works on the same principle, the way each company’s algorithms interpret the data affects the accuracy of the readings, which is all trackers don’t display the same results.

Heart Rate

Fitbit with heart rate sensors will monitor your heart rate at rest – a key indicator of your health. As you get better sleep, these numbers should decrease and the appearance of increased numbers can be a sign that you are experiencing fatigue or sick. This is a powerful indicator and is often underused.

Active Heart Rhythm

You can check your heart rate at any time and the heart rate will be recorded during training. If you are tracking a session, you can find a summary in your Fitbit application and check out the performance of your heart throughout the session.

Why is this useful? You should see that you are getting faster or stronger with the same heart rate that you are getting better with and you can also check whether you have been at rest enough during intense sessions (or did not exceed the limit).

VO2 Max

VO2 Max is also tracked in the app from workouts outdoors using Fitbit. VO2 Max is an estimate of the amount of oxygen your body can process – the more, the better you are. If you work regularly (and we mean the right, intense workouts), you should see that this number will quickly improve.

Heart Rhythm Zones

Your Fitbit can also estimate how much time you spend in each HR zone, which can help you ensure that your sessions meet your goals. Intensive exercise should be conducted in the high zone along with slow jogs. So, for example, you should not go beyond zone 2 or 3. Using heart rate zones can help you prevent excessive training and increase the effectiveness of training.

FITBIT Dashboard & APP Guide

Although all these amazing events are happening on your wrist, the real useful data is stored in the Fitbit app and you can access it and then understand the numbers to help you achieve your goals. We have a complete guide to the Fitbit app, but here’s all it does in a nutshell.

Check Your Daily Statistics

The main Fitbit toolbar is a place where you will receive statistics on steps per day, calories, floors covered and hours of sleep – all this is presented on the main screen of the smartphone application.

Set Your Goals

You can also change your goals in the Fitbit app. While the default targets are 10,000, you can configure these numbers accordingly to help meet your goals. Set your goal and change it – this is the best way to meet your goals.

Check Heart Rate Data

Data on heart rate can be found on the dashboard tab – where you can see your heart rate recording at rest, as well as your VO2 Max, which is renamed the Cardio Fitness Score (although this is just the VO2 number, Max)


A simple achievement of this step every day is not the best motivation, but testing allows you to compete with your physical fitness. You can set your own goals (for example, to achieve a certain distance) or take part in competitions in steps with friends that you add through the application.

Fitbit For Kids

So, if you want to choose Fitbit for kids? Fitbit Ace 2 is designed for six years and older (the original Ace was designed for eight years and older) and is essentially a solid, modular version of the new Inspire family. It covers basic tracking (steps, sleep time and active minutes) and also offers call notifications if they have their phone to connect with.

It complies with all the important rules that apply to children’s trackers, and parents can control the data that is transmitted if confidentiality is important or you’d like to keep better tabs on your child.

Fitbit vs Apple Watch

if you are considering buying a Fitbit, in most cases you are likely to compare it with your closest competitors. Whether it’s a Fitbit smartwatch or a fitness tracker, you can see how they stack up against the Apple Watch – and rightly so.

So, what functions do they have and how do they differ? It depends on the device you are using to compare Apple smartwatches. Take a model such as Charge 3, which in essence is regarded as the best Fitbit for men.

Both devices offer standard activity-tracking features, but the Fitbit device has built-in sleep tracking. Apple can track sleep only through third-party applications and this option is not as convenient as the Fitbit approach.

Have automatic recognition of exercises and are water-resistant for tracking swimming. Battery life varies between the two devices, where most Fitbit devices offer 4-5 days compared to Apple’s 18-hour battery life.

Apple and Fitbit both offer basic features such as notifications, payments, the ability to download applications and the ability to store music and play streaming music. The choice of applications and support for streaming music services is still different.

If you need a built-in GPS, then Ionic is one of the only Fitbit smartwatches that offers this technology. While the Fitbit smartwatch works with iPhones and Android smartphones, Apple works well only with the iPhone.

Support for features may vary when connected to an Android phone or iPhone. For example, sending quick replies from Fitbit smartwatches – this feature is only available for Android devices.

To understand better, we live in such a time that with the help of a fitness tracker or a smartwatch, you can be at ease with regards to your child’s whereabouts. Take a look at the kids GPS watch, with which you no longer need to worry about the location of your child and where they are at any given time.

The same applies to battery life, where just like the Fitbit fitness tracker, Fitbit will give you a lot more. In terms of cost, the initial price for the newest Apple Watch is about 10,000-15,000 thousand rubles more than a Versa and Ionic, so Fitbit watches are a profitable option.

These are just the basic differences, but here’s a bit more!

Fitbit For Swimming

For a long time, we had to deal with Fitbit gadgets, which were good only for protection against sweat. This type of water resistance is still seen in some Fitbit devices, but now there are models with which you can go to the pool and even take with you on a dive.

Fitbit has a 5 ATM waterproof rating. This means that it can be submerged in water to a depth of 50 meters. These are Fitbit Charge 3, Fitbit Inspire, Fitbit Inspire, Fitbit Versa, Fitbit Versa Lite Edition and Fitbit Ionic.

Older Fitbit trackers, such as the Fitbit Alta and Alta HR are waterproof. This means that they can withstand rain, spray, and sweat. If you still want a full-fledged waterproof smartwatch for swimming, then, of course, pay attention primarily to the Apple Watch.

Waterproof devices can track your fitness activity in the water and can record the duration, count the circles and recognize the number of laps. If you love Fitbit smartwatches, you can view some of this data in real-time on the watch screen. To get the most accurate tracking of swimming, you must ensure that the length of the pool is set correctly. Read the Fitbit Pool Length Calibration Guide.
