Breath Hold - FreeDive

Breath Hold - FreeDive is a dedicated breath-hold trainer for freedivers. Improve your CO₂ tolerance and O₂ endurance with structured training tables, voice guidance, and progress tracking. CO₂ TABLES Build carbon dioxide tolerance with fixed hold times and progressively shorter recovery periods. Start with comfortable recovery intervals and let the app guide you through each round. O₂ TABLES Extend your breath-hold duration with increasing hold times and fixed recovery periods. Push your limits safely and systematically. VOICE GUIDANCE Clear voice prompts in Korean and English guide you through every phase - breath prep, hold, and recovery. Train with eyes closed, focusing entirely on relaxation. TRAINING HISTORY Track your best hold times with beautiful charts. View CO₂ and O₂ records separately. Pinch-to-zoom for detailed analysis. SAFETY FIRST Always train with a buddy. This app is for dry land training only. Never hyperventilate. Stop immediately if you feel dizzy or experience abnormal sensations. SUBSCRIPTION & ADS This app is free and supported by ads.
