Don’t forget the apps
A fitness tracker works alongside an app built for your smartphone and other devices. Having solid software to support the fitness tracker will make keeping a tab on your activity far easier. The app, such as the Fitbit, Garmin Connect or Apple’s Health app, can be used to log activity targets and keep a tab on your progress.
What activities can they track?
Most fitness trackers will only be able to break down relatively simple exercises, such as running or cycling, and calculate your calorie burn from this. Many cannot adapt to analysing different lots of types of sport or activity, although some trackers can include walking, running, cycling, weights, elliptical, boxing and swimming.
More advanced fitness tracking devices come with a GPS built-in, others instead link up to your smartphone to provide a breakdown of location data. This can help monitor running, but adding a GPS can add to the price and weight of a fitness tracker.
