Features & Capabilities

Subsurface-mobile is an iOS dive log application based on Subsurface, the best free open source dive log application available on Windows, Mac and Linux. Subsurface-mobile allows you to access your dive log on your tablet or phone, edit the data and even download new dive information from many Bluetooth LE enabled dive computers. Using a free Subsurface Cloud Storage account you can synchronize your dive data with the Subsurface desktop application (while significantly increasing the usefulness, the cloud account is not required to use Subsurface-mobile).

Subsurface-mobile is free and open source. No ads, no commercial anything. And it comes with free cloud storage (if you decide to use that - it's optional). Your data aren't used for anything, nothing gets monetized.

User Reviews

Subsurface-mobile is a strong, open-source dive log app for Apple devices, with cloud sync across Mac, iPhone, iPad and other platforms, plus cross-platform compatibility. Reviewers praise its feature richness, including importing dive profiles from many dive computers, GPS-tagged dive sites, and GPS-exIF integration, along with good developer support. Common caveats are occasional syncing reliability and some users finding the UI clunky or confusing in places. Overall it’s a capable, free logbook that works well across platforms, with room for UX and cloud reliability improvements.
Pros
  • Cloud sync across devices keeps logs up-to-date across macOS, iOS (iPhone/iPad), Windows, Linux, and Android.
  • Cross-platform compatibility across macOS, iPhone, iPad, Windows, Linux, and Android.
  • Open-source and free to use.
  • Feature-rich with dive-computer integration, GPS tagging of dive sites, and multi-format import/export.
  • Responsive, helpful developer/support community.
Cons
  • Syncing can be unreliable at times; cloud save issues reported by multiple reviewers.
  • Clunky or confusing UI in some parts of the app.

For a free dive log app this thing is pretty sweet! The UI is not the prettiest thing you’ll ever see, but what matters is the data and content - and this app does all of that well! I first download the Mac app on my MacBook and I find that it’s easier for me to upload all my dives directly to my MacBook first, and then sync them with the cloud. Once you do that they all become visible here in the mobile app for easy viewing and editing. I hope the developers keep this app current because it’s great!

Wanted to make it work but wasted too much time. Randomly changed dive dates of all dives. Manually corrected only to have them changed again. No support. Not ready for prime time. Look elsewhere.

I use this on my MacBook and iPhone and find it preferable to the SSI and Shearwater apps.
