WARNING: This app is intended for dry practice only. It must not be used during underwater activity, freediving, or as a safety device. The app is not a life-support system and should not be relied upon in any real diving scenario.
Turn your watch into a complete breath training system, not just a timer.
Breath Training System combines structured training, real-time feedback, and adaptive performance modeling to help you improve safely and consistently. Whether you train CO2 tolerance, O2 adaptation, or breath-hold control, the system analyzes your performance and guides your progression without interrupting your flow.
This is not a static plan. The system continuously adapts to you:
Recommends the right session based on fatigue and readiness
Detects plateau, decline, and overtraining risk
Adjusts training intensity in the background
Predicts your next personal best with confidence
Eight structured training paths cover the full spectrum of breath performance development:
CO2 Tolerance
O2 Adaptation
Breath-Hold Control
Breathwork Mastery (multiple methods)
Endurance Mix
Personal Best Training
Active Recovery
Beginner progression
All paths include guided progression and automatic difficulty adjustment.
You always see real progress, not guesswork:
Visual history scaled to your personal best
CO2, O2, and recovery trends from recent sessions
Training state: Recovery, Building, Stable, Peak
Predicted PB based on your performance patterns
