Download and install the app from the Google Play store:
Ensure that Bluetooth is turned ON for your Android device. (You can turn Bluetooth on and off by dragging your finger down from the very top of your screen, or in Settings.)
When you start your first workout, the app will ask permission to use Location. You must select Allow in order for Bluetooth to function with the app. This will allow the app to find and connect to your Bluetooth devices. If you do not see this screen, location permissions can be edited in your device Settings.
