DiveCore — A real dive computer for Apple Watch Ultra DiveCore harnesses your Apple Watch Ultra's water-resistant depth sensor, compass, and accelerometer to give divers everything they need right on their wrist. It pairs with the iPhone companion app in real time and uses on-device AI to help you improve your dive patterns. [ Core Features ] Dive Computer (Apple Watch Ultra) - Bühlmann ZHL-16C with adjustable Gradient Factors - Real-time 16-tissue compartment decompression model - No-decompression limit (NDL) and decompression ceiling - Automatic safety stop countdown (3 min @ 3-6 m) - Ascent rate alarm + haptic warnings - PPO2 oxygen limit alarm - Auto water lock - HealthKit workout session integration - 30Hz smooth digital compass Freediving Mode - Depth disciplines (CWT / CWTB / FIM), static apnea (STA), dynamic apnea (DYN / DNF) - Automatic dive detection for depth, manual timer with lap entry for pool disciplines - Dive count, max depth, surface interval, heart rate, and a per-session log - A session spans many dives: surfacing starts the rest timer, and you end the session yourself - Freedive mode runs no decompression model and no gas or NDL alarms - It cannot detect shallow-water blackout. Never freedive alone, and always dive with direct, trained supervision Estimated Dive Route - Surface GPS captured at entry and exit - Underwater path estimated from compass + gyro + accelerometer + depth changes - End-of-dive drift correction using exit GPS - 3D visualization on iPhone (depth profile walls, drag-to-rotate, pinch-to-zoom) - Insights: average speed, activity level, exploration pattern, current drift estimation This is not real underwater GPS tracking. It is a sensor-fusion estimate based on the diver's magnetic heading and motion, with both endpoints corrected by surface GPS fixes.
