Fast CO2 table & apnea trainer with a clean breath hold timer for freediving.
Run your CO₂ table without watching the clock or fighting a complicated apnea app. CO₂ Table Breath Hold Timer is a fast, reliable interval timer built for structured apnea and breath-hold training. Set your intervals, tap Start, and follow clear audio and vibration cues through every round. Your breath-hold duration stays constant while recovery periods progressively decrease—the proven CO₂ table protocol used by freedivers, spearfishers, and apnea athletes to build carbon dioxide tolerance safely on dry land. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🫁 WHAT IS A CO₂ TABLE? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ A CO₂ table (Carbon Dioxide Tolerance Table) is a specialized breath-hold training routine where hold duration remains fixed across all rounds, but recovery (rest) time between breath holds becomes progressively shorter. When holding your breath, the urge to breathe is triggered by rising CO₂ levels in your bloodstream, rather than a lack of oxygen. By systematically shortening rest intervals, your body and mind adapt to elevated carbon dioxide levels, delaying contractions, reducing panic, and extending your static apnea breath-hold time. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ FAST SETUP & CUSTOM TABLES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Get from opening the app to training in seconds.
