À propos de Breathhold
A breath-hold trainer for freedivers and snorkellers. CO₂ and O₂ tables generated from your own measured maximum rather than from a stock chart, box-pattern preparation breathing, cyclic rounds, and a fully adjustable custom mode. A precise phase timer with a breathing orb, audio cues and haptic transitions, a max-hold stopwatch for personal bests, a multi-week plan, a streak, and a logbook with trend charts. Dry training only unless supervised.
Fonctionnalités
Tables Built From Your Baseline
CO₂ and O₂ tables generated by tested logic from your measured maximum hold and your level, so the progression is yours rather than a stock chart
Five Training Modes
CO₂ tables, O₂ tables, box-pattern preparation breathing, cyclic rounds, and a custom mode with every phase adjustable from 0 to 240 seconds
A Timer You Can Follow With Your Eyes Closed
Monotonic phase timing with a breathing orb, a large countdown, a next-phase preview, audio cues and haptic transitions
Max-Hold Stopwatch
Measure and save your personal best, which then feeds back into every table the app generates
Plan, Streak And Awards
A multi-week progression from your level and goal, a daily streak with a freeze joker, and awards for consistency and volume
Logbook And Charts

Safety comes first, and it is not a formality
Breath-hold training carries real risk, including shallow-water blackout, which gives no warning. Never practise breath-holds in or near water alone or without trained supervision. Dry static training only unless supervised. That notice is shown on first launch, must be acknowledged before the app renders anything, and is repeated in context. Breathhold is a training aid — it is not medical advice and it is not dive instruction.
Tables from your hold, not from a chart
A stock CO₂ table is calibrated to somebody else. Breathhold measures your maximum with a dedicated stopwatch, then generates each table from that baseline and your level, with the phase counts and durations produced by tested logic rather than typed in by hand. As your maximum moves, every subsequent table moves with it.
A timer built for eyes-closed use
The phase timer runs off a monotonic clock so it does not drift, and it announces itself: a breathing orb that expands and contracts, audio cues at every transition, and a haptic pulse you can feel without looking. The next phase is always previewed, so nothing arrives as a surprise.
Never interrupted
No ad ever appears during a breathing or hold session — for immersion, and because an interruption mid-hold is a safety problem, not just an annoyance. Advertising lives on the menu, the logbook, the plan and settings.
