Fitbit is further developing its range of smart health connected watch with sport and health-oriented activity monitoring. Each new model benefits from the experience of Californian company founded in 2007 to improve its performance by keeping the same price. In this fourth version, Fitbit adds a built-in GPS to do without its smartphone for activity tracking.
Fitbit charge 4 design: comfort and lightness
A design similar to that which made the success of the Charge 3 launched in 2024. It remains a model of smart health connected bracelet ultra light and comfortable to wear for the practice of many sporting activities. But, she also takes advantage of a range of accessories to personalize and wear it every day.
- touchscreen
- dial is aluminum s
- scratch resistant Gorilla glass.
The four original finishes:
- Dial in aluminum with black case and bracelet,
- The version violet or “rosewood” according to Fitbit,
- Or the black case and bracelet model Navy blue.
- Finally, a special edition still with the black case, but a woven reflective granite bracelet.
The whole gives off a excellent perceived quality and solidity, even if I didn’t push the Review to make glass scratch or drop tests 2 meters high.

Fitbit Charge 4 takes care of your health
The Fitbit Virtual Coach Charge 4 special edition 2020
The more you wear your watch, the more data it collects to help you progress. For this, it uses the automatic tracking SmartTrack of all your sports activities.
As with the Apple Watch, you will be invited to get up if you are inactive for too long during your day or you relax (guided and personalized wrist breathing sessions, based on your heart rate).
Sleep monitoring and sleep apnea diagnosis
Find out how much time you spend in each sleep phase (light, deep and REM) and benefit from personalized information to set up a more efficient sleep routine.
Fitbit could also use the SpO2 sensor to diagnose sleep apnea after approval from health authorities in the United States.
With this SpO2 sensor, the Charge 4 could give participants of the current Sleep Score Beta Review program very precise information on their state of health, diagnose specific situations and create alerts in the event of a problem.
Women’s health
Use your Charge 4 with the Fitbit app to record your period and symptoms and see where you are in your cycle. For this part (which is not mine, I am not in the target) I invite you to read the paragraph presented during the Review of the Fitbit Versa.
The Fitbit app

The latest update has corrected many synchronization issues.

One of the functions that can be used for all sports activities is Relax
An anti-stress and recovery breathing system based on your heart rate directly displayed on the Fitbit screen. No need to take out your smartphone and launch a dedicated app.
Like on an Apple Watch, you are guided by a small circle that expands when you breathe in and shrinks when you breathe out. If the breathing is well done and deep enough, small stars appear to congratulate you.
How to launch the Relax app on Fibit charge 4
- On your watch, tap the app Relaxed.
- The 2-minute session is the default option. Tap the gear icon or slide your finger to choose to do a 5-minute session. For Ionic and Versa, then press the Back button to return to the Relax screen.
- Tap the play symbol to start the session.
- Stay still and breathe deeply during the calibration period, which lasts between 30 and 40 seconds. The message “detecting your breath” will then appear on your screen.
- When prompted, follow the guide (the circle on your screen) and breathe deeply. You can close your eyes because your device will vibrate to indicate that it’s time to breathe in and out.
- After exercise, a summary will display your alignment (i.e. how closely you followed the breathing instructions), your heart rate at the start and end of the session, and how many days you have worked a guided breathing session this week.
Note: you cannot interrupt the session, but you can cancel it at any time. To exit, press and hold the Back button on your watch.
The app is fine, but it could be improved with all user feedback. Its advantage is that Fitbit has a single mobile app for all of its products. So if you supplement your equipment with a scales like the Fitbit Aria 2 (95 $).

Fitbit charge 4 review
A slight improvement over the Charge 3. We obviously appreciate the addition of GPS and software updates that will benefit the entire range of Fitbit smart health connected watches and bracelets. We can still regret that at this price, the color screen is still not present.
Remains a price significantly higher than the Chinese competition which offers fairly close models for less than 40 $. This is the case for Xiaomi Mi Band 4 and Mi Band 5 to come up,
