Subsurface: An Open-source Multi-platform Diving Logbook for Divers

Subsurface: An Open-source Multi-platform Diving Logbook for Divers

Divers often keep a rich logbook to track their diving activities.  Trainees also are required to have a logbook for their diving training. There are some commercial solutions to do that, but our topic of the day is an amazing professionally designed alternative solution and it's called Subsurface.

Subsurface is an open-source free and genuinely rich diving logbook application for professional divers, trainees and hobbyists. Even though, It has rich features but it comes with a simple easy-to-use interface which does not require much time to learn.

Dive computers with Subsurface

A dive computer takes the depth and time information and applies it to a decompression model to track the dissolved nitrogen in the diver's body during his dive. It tells the diver how much dive time the diver has.
