About AI Apnea Trainer
For freedivers, spearfishermen, and all athletes who want to control their autonomic nervous system to enhance performance. AI Apnea Trainer uses the practical disciplines of freediving training to transform your daily practice into a steady, visualized journey of growth. [ Key Features ] ■ Intuitive Dashboard & Modern Navigation (New) - Completely redesigned Home dashboard and Logbook. Review your daily progress and performance trends more beautifully and intuitively than ever. ■ Dry Apnea Training Comprehensive support for dry training, from planning and execution to AI-driven menu updates. - Unlimited Table Creation (O2 / CO2, NC, etc.): Create and save unlimited custom tables tailored to your goals, building an unshakeable training plan. - MAX HOLD Mode: Test your personal best and understand your current limits. Records and supports the full breath-hold cycle from Breathe-up to Recovery. - NC Mode (No Contraction Mode): Build CO2 tolerance through repeated sub-maximal holds that stop before the contraction threshold. Accumulating rounds without contractions safely adapts your body to CO2 and gradually extends your pre-contraction time. - AI Coaching: Analyzes your session history and perceived exertion to suggest the optimal next training load — fostering steady growth without rushing your progress. - Absolute Immersion with Audio Cues: Clear audio leads your session so you never need to look at the screen — supporting fully eyes-closed training with smart background playback. - Live Activities: Track your current phase and remaining time in real-time right from your Lock Screen or Dynamic Island. - Apple Watch Sync & Haptic Guide: Syncs in real-time with your iPhone to record heart rate during sessions. Wrist vibrations notify you of phase transitions, so you can stay completely relaxed and immersed. ■ Ocean Logs & Advanced Visualization - Ocean Log Import: Supports .fit, .uddf, and .xml logs. Import directly from your dive computer apps via Share Sheet for seamless visualization. - Analytics & Dive Comparison: Profile charts for depth, heart rate, and descent velocity. Compare past dives with marine conditions (weather, tides) to plan your next session. - Dive Bookmarks: Bookmark important dives or personal bests for instant access. - AI Coach Dive Analysis: After each logged dive, the AI Coach automatically generates a personalized coaching comment — highlighting what went well and flagging any risk points in your profile. - Dive Stamp & Social Share: Create stylish dive stamp images from your log data and share them directly to Instagram Stories or any social platform. Customize style, color, and discipline to make every dive memorable. [ Who is this for? ] - Freedivers looking to extend their dive time and build mental discipline. - Spearfishermen wanting to improve silence and efficiency underwater. - Athletes mastering autonomic nervous system control through breathing techniques. - Anyone who wants to make meditation and breath-hold training an unshakeable habit. [ Important Safety Warnings ] - Freediving and breath-hold training carry risks such as blackouts (loss of consciousness). - Never practice alone in the water: Always have a buddy when practicing breath-holding at the surface. - Ensure a safe environment: When doing dry training, always practice sitting or lying down on a soft surface like a sofa or bed to prevent falls and injuries. - Take professional courses: This app is a training tool and NOT a substitute for proper education. We strongly recommend seeking instruction from knowledgeable and experienced freedivers. - Never push beyond your limits. If you feel dizzy or unwell, stop immediately. By downloading this app, you acknowledge and agree that you assume full responsibility for your own safety and health during training. Your deep self-understanding expands your potential. Elevate your daily routine to a deeper, quieter dimension with AI Apnea Trainer.
What’s new
Version 1.5.5 · Updated October 15, 2026
DIVE ANALYSIS - New DEPTH SPLITS in dive detail: descent and ascent speed and average heart rate for every 10 m (dives of 20 m or deeper). Tap a row to highlight that section on the charts. - Velocity and water temperature now share one chart. - Heart rate uses one dedicated color on every screen. - Export a single dive as JSON from the Export menu in dive detail. - Copy training and ocean logs as structured JSON. - Better UDDF import compatibility. AI COACH - The app now asks for your consent before sending data to an external AI. You can withdraw consent in Settings. - Log incidents per dive (Early turn / EQ trouble / Blackout / LMC / Squeeze and more). Reports that may need medical attention are not sent to the AI; guidance is shown on your device instead. - Reviews are now split into Observations, Interpretation, Next Focus and Safety Notes. Safety Notes come from fixed rules (such as AIDA surface intervals), not from the AI. TRAINING - Session results compare your total hold time with your last session of the same table. - PB results show this attempt, your previous PB and the difference. - Logs are now confirmed with a long press. - Table type and hold mode selectors now use text labels only. FIXES - Fixed a new PB record being lost when results were discarded without a prompt. - Fixed the session type being detected wrongly when a table was named "MAX HOLD". - RESET during a session now asks for confirmation. DESIGN & ACCESSIBILITY - Supports Dynamic Type. - Added VoiceOver labels, and the PB screen now supports Magic Tap. - Blinking and motion are reduced when Reduce Motion is on. - Small buttons have larger tap areas. - Unified colors across iPhone, Apple Watch and Live Activities.
