Apnea training for iPhone + Android
Train your breath hold with a plan.
Run guided CO₂ and O₂ tables, test your current baseline, and keep every completed session in one place.
A repeatable training loop
Know what to do next.
Set your baseline
Use a max breath-hold or CO₂-baseline test to establish a current reference before choosing a table.
Run the right session
Choose a CO₂ or O₂ table, edit the intervals when needed, and follow each phase with on-screen timing and sound cues.
Review the work
Completed sessions and tests stay in your history, so your next decision is based on what you actually trained.
Inside the app
Built around the session.
No spreadsheet beside the timer. BreathHold keeps the table, phase timing, cues, and session record together.
Follow without staring
Sound cues mark training phases while you remain settled.
Adjust the intervals
Edit custom sessions instead of forcing every day into one preset.
Start on the web
Build the table before you train it.
Generate a conventional CO₂ or O₂ progression from your current hold, review every round, then train only when the setup makes sense for you.
Example cycle
Train with the safety rules intact
Dry land when alone. A trained buddy in water.
Never practise breath holding in water alone. An app or timer does not replace trained in-water supervision.
Learn before you hold
Plain-language training guides.
How to hold your breath longer
A practical guide to preparation, dry-land practice, recovery, and common mistakes.
