Diver Planner is not a medical device and does not replace a real dive computer. Always dive within your training, certification and equipment limits.

What’s new

Reverse gas planning: enter a target depth and bottom time and the planner recommends a best-mix gas set (back gas, travel and deco gases) plus tanks — deep trimix gas planning in a few taps. This release also improves decompression-calculation accuracy and adds a configurable rock-bottom (minimum-gas) reserve model.
