STABuddy

STABuddy is a static apnea trainer built for pool sessions. Build your table once, press start, and put the phone down — the voice does the rest.

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.

Loud enough for the deck Route audio to the phone speaker or any Bluetooth speaker. Set an audio offset to compensate for Bluetooth latency so the cues land on time. The session keeps running with the screen awake or the phone in your bag.

Share with your buddy or coach Export any training as a .stat file. AirDrop it, message it, save it to Files. Tap to import on the other side.

Nothing in the way No accounts, no cloud, no tracking. Your trainings live on your phone. Two built-in tables get you started.

Never train static apnea alone. Always have a trained buddy watching you, within arm's reach, for every hold. STABuddy times and cues your session; it cannot supervise you.
