Diver Planner

Serious dive planning, from your first to your deepest.

Diver Planner brings dive planning, logging, trips, gas blending and safety info together on mobile — and imports your Shearwater dive computer logs. Grow from your first nitrox dive to trimix decompression in one app.

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