Did an interval running session and locked my phone however beeps do not go off when phone is locked only when the app is opened. Running session didn’t go well due to not knowing when to run hard and when it was rest. Had to adjust and leave phone unlocked and phone running, which used a lot more battery.
Other than that it’s a great and easy to set up an interval session. Just makes beeps louder as when music is playing it’s hard to hear and make it that the beeps go off when phone is locked
