Static Apnea Trainer
Dry breath-hold training with CO2/O2 tables.
Follow guided static apnea sessions, calm cues, a beginner plan, and progress that favors controlled dry practice over record chasing.
For dry practice only. Never practice breath-holding in water without qualified supervision.


A focused apnea trainer for dry sessions.
Static is built around the core training patterns people search for: CO2 tables, O2 tables, guided breath-hold timers, reminders, and simple progress without pressure to chase maximum attempts.
Preview structured rounds and train with clear prepare, hold, and recover phases.
Use a plan-first flow so today’s session is obvious before settings and custom tables.
Spoken, haptic, and visual cues help you stay oriented without staring at the screen.
Track completed sessions, effort, and history on-device by default.
Designed for the session, not the noise.
Large timers, simple choices, and high-contrast states keep the app readable during seated or lying-down dry training.





Dry-only safety posture.
Static is a training timer and journal, not a medical device, blackout predictor, or water-safety substitute.
Train seated or lying down, away from water.
Breath-hold practice can be dangerous. Static keeps safety visible and avoids claims about guaranteed performance or safe solo in-water training.
- Never practice breath-holding in water alone.
- Do not hyperventilate before a hold.
- Stop if dizzy, unwell, confused, or in pain.
- Use qualified supervision for in-water freediving or spearfishing training.
