Does my phone need to be unlocked to use the OxyKnight® Watch App? Do I need to leave the OxyKnight® Watch App open on my phone to record my health data?

No, your phone does not need to be unlocked once data has started recording to the app. You do need to leave the OxyKnight® Watch app open on your phone for data to be recorded to the app. But data will still be recorded to the app if the phone goes into sleep mode.

However, for best practice and best results with minimum chance of connection interruption, we do recommend if you are taking a long and continuous test that would be at least 6 hours that you keep your application open and phone on.
