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…
