The Fitbit Charge 2 tracks your heart rate and number of steps that you take every day. This information is then used to determine how many calories you burned. It has built-in reminders to move if you have been sitting too long that can be enabled. It will also automatically categorize exercise in the app.

The Fitbit Charge 2 also has sleep analysis that can measure sleep duration and consistency. It can also give you data on your REM cycles and wake you up with a silent vibrating alarm on your wrist.

Another amazing feature is call, text, and calendar notifications. You can get these without pulling out your phone, which is super convenient.

Fitbit Charge 2 vs. Fitbit Alta HR

Fitbit will also be selling the Alta HR for the same price of $99 for Black Friday. These smart watches have the same functionality until so far, but there are major differences. The biggest difference is that the Fitbit Alta HR is significantly smaller than the Fitbit Charge 2. This can be a make or break feature for people who don’t want something too large on their wrists all day.

There are two other features that the Fitbit Charge 2 has other than a larger screen. It has connected GPS which allow you to connect your tracker to your phone and get real-time exercise stats like pace, distance, and a map of your route after working out.

The Fitbit Charge 2 also has a new feature called guided breathing sessions. These help you find moments of calm based on your heart rate throughout the day. The Charge 2 will remind you to take a minute to destress at the worst times of the day.

Both watches are really awesome and they share most features. It just comes down to personal preference, although if sales count for anything, the Charge 2 is definitely more popular for most people. The Charge 2 is small and light-weight enough that you won’t even notice it’s there.
