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.
### Safety First
BreathHold Coach is designed for dry (out-of-water) apnea training only and does not promote unsupervised in-water breath-hold activity.
