Daily breath training for freedivers, scuba divers, and anyone looking to improve breath control. Five core exercises cover everything from beginner box breathing to competition-style apnea tables. CORE EXERCISES • Box Breath — Equal-ratio breathing for calm focus • Breath-Up — Pre-dive preparation sequence • Air Save — Continuous cadence for efficient air use • CO₂ Tolerance Table — Decreasing rest intervals to build CO₂ tolerance • O₂ Tolerance Table — Increasing hold times to extend breath capacity ADVANCED TRAINING For experienced divers: structured programs including Frenzel and mouthfill equalization drills, pre-dive routines, static apnea intervals, and mammalian dive reflex conditioning — all designed for safe, dry-land practice. BUILT FOR CONSISTENCY • Session history with personal bests • Daily training streaks with unlockable sea creatures • Fully adjustable timings for every exercise • Quiz mode to train focus under breath-hold pressure • Ambient soundscape with meditation gong cues • Haptic feedback guides you through each phase All training is intended for dry land only. Never practice breath-holds in water without supervision.

Not a diver but I love this

I don't dive at all but my freediver friend wouldn't shut up about this app so I tried it. The Box Breathing mode is amazing for anxiety. I use it before meetings and before bed. The circle animation is calming, the haptic taps keep me in rythm, and there's a little sea creature that swims around while you train which is a fun thing to unlock and keep me consistent. Simple, beautiful, works.

Cut my air consumption on every dive

The Air Save mode is a 1:2 inhale-to-exhale trainer and it genuinely improved my SAC rate. Practiced 10 minutes a day for two weeks before a liveaboard and my air lasted noticably longer on every dive. The breathing circle and phase beep keep you on cadence perfectly. Runs continuously with no round limit. Simple concept,gets results.

This update brings small fixes and refinements: - Improved stability during breathing and training sessions - Minor visual and wording polish
