## What is Holdfast?

Holdfast is a calm, focused breath-hold trainer for freedivers, spearos, and anyone learning to sit comfortably with the urge to breathe. Run proven CO₂ and O₂ tables on your iPhone — or entirely on your Apple Watch, screen-off and haptic-guided — so every session feels effortless.

WHY HOLDFAST
- CO₂ tables to blunt the urge to breathe; O₂ tables to extend your hold.
- Guided sessions with gentle haptic and audio cues — eyes closed, no screen needed.
- Built for Apple Watch: start, run, and finish a full session from your wrist, screen-off, driven by taps.
- Progress that motivates: history, streaks, personal bests, and clean charts.
- Heart rate during holds via Apple Health (optional).
- 100% offline. No account, no sign-up, ever.

FREE FOREVER
- The full CO₂ and O₂ table trainer, on iPhone and Apple Watch.
- Session history, streaks, and personal bests.

HOLDFAST PREMIUM
- Custom table builder — design your own ramps.
- Training plans — structured, progressive programs.
- Advanced analytics — deeper trends and recovery insight.

TRAIN SAFELY
Holdfast is for dry training only. Never practice breath-holding in or near water alone, and never hyperventilate. Shallow-water blackout gives no warning. Stop immediately if you feel dizzy, lightheaded, or tingling, and talk to a doctor before starting breath-hold training if you have heart, lung, blood-pressure, or pregnancy concerns.

PRIVATE BY DESIGN
Everything runs on your device. No account, no tracking; your health data stays in Apple Health.
