Fitbit also tracks water intake. A simple click of a button allows you to add water that you’ve consumed. And it keeps you working toward the app’s goal of 64 ounces daily.

Further, you can track exercise through Fitbit. This makes exercise even more fun because a simple click (on some devices) or visit to the app will show exactly how many calories are being burned in a workout. Then you can review your workout later to see how you did in terms of heart rate and overall calories burned. And you can scroll through the app to compare calories burned in workouts throughout the week. It also keeps a record of when you’ve worked out, making it easy to determine how many workouts you’ve completed each week. 

Fitbit Challenges

The Fitbit also issues challenges. You can pick a number of options, from daily goals to “Weekend Warrior” challenges. And you can bring your friends in on the action by adding them as friends on the app and following their progress. For example, in the “Weekend Warrior” challenge, you compete against friends to see who meets their personal daily step goal. Up to 10 friends can be a part of the process, making it a fun competition with overall health in mind. 

One of the most interesting of Fitbit’s capabilities is the heart rate feature. Whereas we once had to wear straps on the chest to monitor heart rate, it is now much easier with this device. In fact, it tracks your heart rate on your arm or wrist, depending how high up on your arm you wear it. That said, it’s easier to wear it higher up on the arm during a workout because it won’t slip and lose track of the count. 

Fitbit has even been used to solve criminal cases -- and not always in the favor of the accuser. According to NBC News, one woman’s accusation of criminal assault was disproved by her device. The woman claimed that she was pulled out of bed and then sexually assaulted. But her Fitbit showed that she was awake and walking around at the time of the accusation, which proved her claim was false.
