While this app is primarily designed to work in conjunction with the brand’s line of fitness trackers, you don’t need one to benefit from its features. The app can use the sensors in your smartphone to count the number of steps taken each day, as well as monitor your activity routes using the device’s GPS.
The Fitbit app also makes it easy to track your calorie intake with its food log feature. Additionally, it offers the option to record and monitor other health information such as your weight, blood pressure and glucose levels. The app is free to download from the Android and Apple app stores.
