BreathHold Coach

Train smarter, hold longer. Structured CO₂ and O₂ tables for freedivers, spearfishers, and breath-work athletes.

BreathHold Coach

BreathHold Coach is a dry apnea training app built for freedivers, spearfishers, swimmers, and anyone looking to safely improve breath-hold performance through structured land-based training.

Train with guided CO₂ and O₂ tables, create fully custom sessions, and track your progress over time with detailed stats and performance insights.

Training Tables

CO₂ Tables Improve tolerance to rising carbon dioxide levels with fixed hold times and progressively shorter recovery periods.

O₂ Tables Build oxygen endurance through increasing hold times with consistent recovery intervals.

Custom Tables Create personalized training sessions with fully adjustable hold and recovery durations.

Adaptive Progression

Training recommendations adapt based on your recent performance and consistency, helping you progress at a sustainable pace.

Guided Training Sessions

Optional pre-session safety checklist, countdown timers, haptic feedback, and audio cues help keep every session focused and structured. End rounds early at any time while still recording your actual hold results.

Progress Tracking

Monitor personal bests, session history, completion rates, and detailed round-by-round performance. Visual charts help you track consistency and long-term improvement.

Achievements

Unlock milestones for streaks, training consistency, and performance improvements as you progress.

Apple Health Integration

Optionally sync workouts with Apple Health and read resting heart rate data. All training data stays stored on your device. No account required.
