Subsurface is an open source dive logbook for scuba, rebreather, and free divers. Track your dives by logging locations (with GPS coordinates), gear, exposure protection used, divemasters and dive buddies, plus your own notes and ratings for each dive. Subsurface also allows you to plan your dives, by providing a comprehensive dive planner that includes support for multiple gases, deco planning, and more.
Dives can be downloaded from a variety of dive computers, entered manually, or imported from other dive log applications.
