With smartwatches, it is about onboarding as many premium features as possible. The fitness wearables market is getting fiercely competitive with every new device that is launched. I used it to test its sleep tracking feature and in my experience, it is comfortable enough such that I didn't want to rip it off my skin at any point, which says a lot about it. Overall, Charge 4 is comfortable to wear even at night when it tracks your sleep quality.

This means that occasional splashes of water be it in the form of rain or pool water should do no harm to it. Fitbit says that the Charge 4 is water-resistant up to 50 meters and it can track your swim workouts as well. It is comfortable to wear no matter what you are doing or what circumstances you are using it in, even in the rain. Charge 3 features a design that is comfortable to wear even for long durations. Charge 4 ships with Silicone strips in two sizes and you get three colour variants to pick from - Black, Black dial with Stormy Blue straps, and Rosewood.Īll of this, barring the colours, of course, are similar to what Charge 3 offers. The touch-based controls are equally proficient at doing their job and they function without missing a beat every time.Īt the bottom of the dial, you get the charging pin along with a bunch of sensors and on the left side, there is a haptic touch button that lets you navigate the fitness tracker's interface with ease. The display is bright and clear and it is easily visible under the sun. This means that you get a 1-inch Black and White OLED display that is encased in an aluminium chassis. The Fitbit Charge 4 features a design that is quite similar to Charge 3.
