## Description

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.
