About this app

Underwave Training is a breathwork and breath hold training app built for surfers, freedivers, swimmers, and water sports athletes.

No login. No account. No internet required. Download and train.

― BREATHING EXERCISES
Configure any breathing pattern: Inhale / Hold / Exhale / Hold. Set rounds, rest time, and let audio guide every phase. Works with screen off. Won't interrupt your music.

― TEST BREATH HOLD
Ascending counter for max holds, BOLT tests and relaxation assessments. Set preparation time, configure audio alerts at specific timestamps.

― BREATH HOLD TABLES
Build your own CO₂ tables, O₂ tables, or any custom protocol. Create, save and run structured breath hold sessions with full audio guidance.

Built for real training — not meditation apps.
