DiveCore — Dive Computer for Apple Watch Ultra DiveCore uses your Apple Watch Ultra's depth sensor, compass, and accelerometer to show your dive on your wrist.

[ 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, credited with shallow deco stop time) - 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 at entry and exit; underwater path estimated from compass, motion and depth, then drift-corrected with the exit fix - 3D route view on iPhone with insights (speed, activity, pattern, current drift) This is not real underwater GPS tracking.
