Apnoia: Breath Hold Training

Extend your breath hold with structured training.

Apnoia brings the CO2 and O2 tables used in freediving and static apnea training to your phone. Set your hold time, follow the guided sequence, and track your progress over time.

WHAT'S INSIDE

CO2 tables — fixed hold time with progressively shorter rests. Trains your tolerance to rising carbon dioxide, the urge to breathe that ends most attempts before your body actually needs air.

O2 tables — fixed rest with progressively longer holds. Trains your body to work with less oxygen.

Custom tables — build your own sequence if the presets don't match where you are.

Voice guidance — every phase is announced out loud, so you can keep your eyes closed and stay relaxed. No need to watch a screen while you hold.

Session history — every table you complete is saved. See your best holds and how they change over the weeks.

WHO IT'S FOR

Freedivers and spearfishers preparing for deeper, longer dives. Swimmers and underwater hockey players working on breath control. Surfers training for hold-downs. Singers and wind players building lung capacity. And anyone curious about how long they can actually hold their breath.

No experience needed. Start with a preset table and work up.

HOW IT WORKS

Everything runs on your device. No account, no sign-up, no ads, no interruptions. Apnoia only connects to the internet when a feature requires it, and it tells you when that happens.

Available in 13 languages: English, Turkish, German, French, Russian, Italian, Spanish, Portuguese, Indonesian, Japanese, Korean, Arabic and Polish.

SAFETY FIRST

Apnoia is built for dry training only. Never practice breath holds in or near water, and never train alone. Blackout can happen without warning and with no sensation beforehand. Always train with a qualified partner present when you are in the water, and get medical clearance if you have any cardiovascular or respiratory condition.
