Subsurface is a free, open-source dive log application for recreational, technical, and free divers that runs on Windows, macOS, Linux, Android, and iOS. It downloads dives from dive computers, imports logs from other programs, plans dives with Bühlmann ZH-L16 or VPM-B models, and computes dive statistics.
Use cases
- download dives from my dive computer
- log and organize scuba dives across devices
- plan a technical dive with Bühlmann or VPM-B
- import dive logs from other divelog software
- track dive statistics like SAC rate and gas pressures
- view my dive log on my phone
- store my dive logbook in the cloud
When to choose
- you need a free cross-platform divelog not tied to a specific dive computer brand
- you are a tech diver needing deco planning with VPM-B or Bühlmann ZH-L16
- you want cloud sync and mobile access to your logbook
When to avoid
- you need a commercial product with vendor support
- you only want a simple paper-log replacement without dive computer integration
