Build the table Rounds are simple: breathe-up, then hold. Add rounds, set each duration with an mm:ss picker, step up the holds by 30 seconds, duplicate the last round, or set every breathe-up at once. Totals and start times update as you go. Press start, put it down A huge timer you can read with wet eyes. The whole screen changes colour with the phase — light while you get ready, ink while you breathe, red while you hold — so your buddy sees where you are from across the lane. Pause, skip, or end at any time. Spoken cues, freediving protocol Breathe-up counts down to official top: every minute, 30, 20, 10, then five to one. Apnea counts up: minute marks, the final thirty and fifteen, then the countdown to "finished". Optional plus counts after official top. Choose a male or female voice and preview it.
