Divecommand

Dive Command is a recreational dive planner built on the Bühlmann ZHL-16C algorithm with adjustable gradient factors (GF 40/85 default) — the same decompression model used by Garmin, Suunto, and Shearwater dive computers. Stop squinting at plastic no-decompression tables and plan with the same math your dive computer uses. PLANNING • No-Decompression Limits (NDL) for air, nitrox (EAN32/36/custom), and trimix • Multi-level dive planning with surface interval calculations • Altitude corrections for high-altitude diving • Salt/fresh water and imperial/metric support • CNS O2 toxicity tracking • Gas planning with rock-bottom / minimum gas calculations • Technical mode: custom gradient factors, multi-gas switches, deco ceiling DIVE LOG • Log actual dives against your plan — depth, bottom time, SAC • Attach GPS coordinates for entry/exit points • Attach a photo to each log entry • Track NDL exceedances and dive history stats over time NATIVE iOS FEATURES • No-fly countdown on your Lock Screen and Dynamic Island • A notification the moment you're clear to fly, even with the app closed • Home Screen widget showing your no-fly countdown at a glance • Haptic feedback when a dive plan requires decompression, and when you save a log entry • Share a dive plan or log entry — site, buddy, depth, SAC, GPSh the native iOS share sheet Dive Command matches the numbers your dive computer already shoheck your plan before you get in the water — not just after.
