Divecommand
Utilities
Free · Designed for iPad. Not verified for macOS.
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.
