Great app

Love the app. Two additions I see are to be able to add a different sound for 1) the recovery period beep and 2) the three second beep leading into the recovery phase. But the other features like playing music of my choice and working in the background/locked (pro) are awesome.
Perhaps in the future Ill be able to record voice prompts of my own and incorporate them into the timer as motivation or in addition to the rest, exercise prompts currently available.
