;Fitness trackers aren’t sophisticated enough to measure results from specific exercise routines. Most of them offer heart rate monitoring and a record of the amount of time spent moving. Pairing the tracker with a good app can help you judge your success in an exercise program. For example, if you have a Fitbit, the Fitbit app is a great place to start. You can download the Fitbit app for free to your Android or iPhone. It’s important to realize that health tracking cannot be achieved with this technology alone. We recommend that you share your fitness goals and data with your physician to maximize best results.
