The Turn is a freediving training companion built for divers of all levels — from first breath-holds to competition depth. Track every session, monitor recovery, and receive AI-powered coaching feedback tailored to your training. Whether you're training in the pool or open water, The Turn keeps your progress clear and your focus deep. TRAINING LOG Log line dives (CWT, CNF, FIM) and pool sessions (STA, DYN, DNF) with depth, distance, and personal bests tracked automatically. Record adventure dives, spearfishing, and scientific exploration sessions. APNEA TABLES Run O2 and CO2 tables with a built-in timer. Tap the screen to record contractions during each breath hold. Track historical averages to measure tolerance progress over time. AI COACHING Receive a personalised debrief after every session — performance analysis, recovery status, and recommendations for your next session. Powered by Claude AI. RECOVERY TRACKING Log your daily resting heart rate to monitor fatigue and readiness. Sync with Apple Health for automatic RHR data. PROGRESS CHARTS Visualise depth progression across all disciplines. Track lung capacity, VO2 max, CO2 tolerance, and flexibility over time.
