Design and screen

Fitbit Charge 3: 18.325mm wide, available in small and large sizes.
Fitbit Charge 2: 21.45mm wide, available in small, large and extra-large sizes.

In terms of design, they are pretty similar. Both have a rectangular screen and a band that is as wide as the body, though the Charge 3 design has been refined and tweaked to make it look more futuristic.

One difference is that the newest Charge 3 is a bit thinner, looking better on your wrist and not so bulky. At the same time, it is lighter since it is made from aluminum instead of the stainless steel that the Charge 3 is built on.

But the biggest difference comes on the screen. The Charge 3 sports 40% bigger display than the Charge 2. One thing that was not improved is the black and white from the screen, although the Charge 3 has a resolution boost.

A cool improvement is that the display is now 100% touchscreen so you will be able to scroll down and choose apps, instead of the Charge 2 where you can only tap on the screen to switch what it is displayed but that is about it.

Fitness Tracking

The Fitbit Charge 2 is one of Fitbit best sellers for a lot of reasons. Firstly, it is affordable. Secondly, it comes with cool features such as heart rate monitor, step and calorie tracking, sleep tracking, and a SmartTrack that can recognize automatically your sport or exercises.

The Fitbit Charge 3 comes with all the same features but with one big improvement: it is waterproof up to 50 meters!. So now you can track your swims or wear the tracker 24/7 even in the shower.

The latest technology that comes with the Smartwatches ( Ionic and Versa) is also available in the Charge 3, with the addition of the Female Health Tracking function that will control the ovulation cycles and learn from them.

There are some extra functions that you can perform right from your watch, for example, you can set goals without heading to the app. Some versions of the Charge 3 also include the NFC payments so you will be able to use Fitbit Pay and pay for anything right from your wrist.

One thing to have in mind is that neither the Charge 2 or 3 comes with built-in GPS, so if you want to track your runs accurately, you will need to bring your phone to pair the watch with it and have GPS tracking on.

However, it is a new model that normally comes with some issues that Fitbit will take care in the long run.
