Hold your breath longer, and stay calm doing it.
Anima Apnea is a static apnea trainer for iPhone. A breath-hold timer that logs your contractions, CO₂ and O₂ tables built from your record, guided breathing and 4-week plans.
Free to download. Works offline.
Sit comfortably, breathe out gently, then hold. Let go when you breathe.
Every hold has three phases.
Knowing where you are in a hold is what lets you relax through it. Anima's timer is built around these moments.
Easy phase
No discomfort yet. Oxygen is plentiful and the only job is to stay loose: jaw, shoulders, hands.
First contraction
Your diaphragm twitches on its own. It's rising CO₂, not a lack of oxygen. Tap the screen and Anima records the moment.
Struggle phase
Contractions come closer together. Training is about letting them pass without tensing up, and seeing that first tap arrive later over the weeks.
Tables built from your record.
Enter your best static hold and Anima builds your CO₂ and O₂ tables. Then it times every round for you with sound and haptic cues, so you never watch a clock.
- CO₂ table: the hold stays the same, recovery gets shorter. Trains your tolerance to the urge to breathe.
- O₂ table: recovery stays the same, holds get longer. Trains you to go further, safely.
- Your own tables: change hold, recovery and round count whenever you want.
Breathe well before you hold.
A calm, slow breath-up sets up a better hold. Pick a pattern and follow the guide, or build your own rhythm.

Long exhales to slow everything down.
