Fitbit has been a star in the wearable fitness tracker scene for quite some time. No wonder - it was one of the first devices that was small and pretty enough to be worn around the clock and it is able to track both activity and sleep.
Fitbit’s strength is that its functionalities are very simple due to the single-button control. Each press of the button cycles the display (OLED) through one of six modes (steps, distance, floors climbed, calories burned, flower (overall recent activity level and clock). Yet the device collects an immense amount of data that can nicely be viewed in several Fitbit apps or the Fitbit web application. Additionally, even more details can be logged, such as individual foods and workouts from your smart phone or computer. And weight and other health indicators such as blood pressure, glucose, and heart rate can be included as well.
