DeepBreath: Apnea & CO2 Tables

About

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.
