The app is created for:
2. iPhone 5 or newer with iOS 10.3 or higher.
The app requires that you allow the app to collect location data in the background in order to work. Otherwise, when your phone is in your pocket while you travel, it won't be able to collect your trips.
The app can also be used on iPad and on Android tablets as long as they have GPS hardware (some iPads do not have GPS). The user interface is optimized for phones but is available on tablets too.
