NeuraTiM DecoLab

Plan one dive, compare six decompression models, explore gas choices, and fly a live simulation — all offline, with no account, ads, analytics, or tracking.

DecoLab is a complete dive-planning toolkit for recreational and technical divers. It brings NDL calculations, decompression planning, gas management, cylinder planning and live dive simulation together in one place.

Use DecoLab to: • Calculate no-decompression limits for different depths and times • Build complete multilevel and decompression dive plans • Review the first stop, time to surface, total runtime and ascent schedule • Plan Air, Nitrox and Trimix and calculate MOD, END and EAD • Calculate SAC, RMV, gas consumption and required reserves • Manage cylinders, gases, stage bottles and gas switches • Track CNS, OTU and tissue loading • Calculate maximum bottom time based on gas, reserve and profile • Save reusable diver, cylinder and gas configurations • Print or share complete plans with every calculation parameter included

The live simulation cockpit lets you run a dive profile from 1× to 30× real time. Change depth or gas during the simulation, test scenarios such as losing a stage cylinder, and immediately see the ceiling, decompression stops, time to surface, gas use and remaining gas update.

Recreational divers can use DecoLab for NDL, Nitrox and gas-consumption planning. Technical divers can build multilevel, multigas and decompression plans with complete management of cylinders, reserves and gas switches. Results from multiple calculation methods can also be compared when needed, but the main purpose is to provide all essential dive-planning and calculation tools in one app.

Your data stays on your device and no account is required. Backups can be stored as readable files or protected with AES-256-GCM encryption.

Important: DecoLab is a planning and teaching tool, not a dive computer. It does not replace proper training, a dedicated dive computer or independent plan verification. Decompression diving can cause serious injury or death. Always cross-check every plan with an independent source and dive only within the limits of your training and experience.
