Plan recreational and technical dives on iPhone and iPad. Bring NDL, decompression schedules and gas calculations together—offline, with no account. Plan the dive Create multilevel profiles with air, Nitrox or Trimix. Review stops, time to surface, total runtime, gas switches, consumption and CNS/OTU exposure. Start with Recreational tools or switch to Technical for advanced planning. Know your gas Estimate maximum bottom time from your profile, cylinders and reserve. Calculate SAC/RMV, MOD, END, EAD and oxygen partial pressure. Keep a gas and cylinder library and reuse tank configurations. Compare and learn Explore six decompression models with supported dive profiles: Bühlmann ZH-L16C and ZH-L16B with gradient factors, VPM-B, VPM-B/GFS, RGBM and the US Navy Standard Air Decompression Table. Inspect schedules and results instead of relying on one headline number. Blend and simulate Calculate partial-pressure fills and cross-fill blends. Replay a plan or control depth manually in the simulation, watching the profile, ceiling, tissue loading, oxygen exposure and remaining gas change. Keep your plans Save, export and share plans. Data stays on your device; backups can be readable files or protected with AES-256-GCM encryption. No account, advertising, analytics or tracking. Optional feedback is sent only when you choose to submit it. DecoLab is a planning and teaching tool, not a dive computer. It does not replace training, a dedicated dive computer or independent plan verification. Decompression diving can cause serious injury or death. Cross-check every plan and stay within your training and experience. Every feature is free. You can support the NeuraTiM project once or monthly; support unlocks nothing.
