Why Spearo Apnea?
Built by spearos, for spearos. Every feature earns its place.
CO2 Tolerance Tables
Progressive CO2 tables that shorten rest while keeping hold times constant. Build tolerance to the urge to breathe, the key to longer, calmer dives.
O2 Training Tables
O2 tables lengthen your holds while rest stays constant, so you extend your max hold step by step.
On Your Wrist
The watch apps run on their own on Apple Watch and Wear OS. Start a table and follow the cues through every breathe, hold and rest phase.
A Coach That Plans Your Week
Find your baseline, then get a training plan that adapts to how your sessions go, with rest days built in.
Track Your Progress
Best hold, score and training volume over weeks and months, so you can see exactly how far you've come.
Train Safely
Never train breath holds in water alone. The app walks you through the rules before your first session: dry tables only, and stop at the first sign of dizziness.

Frequently Asked Questions
Which devices does Spearo Apnea run on?
The watch apps run standalone on Apple Watch (App Store: Spearo Apnea) and Wear OS (Google Play: Spearo Apnea Trainer). The phone app, with the same training plus the coach and full history, is live on Google Play as Spearo Apnea and coming soon to the iPhone.
What are CO2 and O2 tables?
CO2 tables build tolerance to carbon dioxide by shortening the rest between holds. O2 tables extend your max hold by lengthening the holds. Both are standard freediving training methods.
Is this safe for beginners?
Yes, on dry land. Tables start from your own baseline. Never train breath holds in water alone, and always dive with a buddy.
Is it free?
Free to start. Apnea Pro adds the Pro tables, the coach and AI-built tables, for $4.99 a month or $24.99 a year.
