Subsurface-mobile

Subsurface-mobile is a full-fledged dive log application for Android, based on Subsurface, the best free open source dive log application available on Windows, Mac and Linux. With Subsurface-mobile you can access your dive log on your tablet or phone, edit the data and even download new dive information from many Bluetooth, Bluetooth LE, and USB serial dive computers. Using an optional 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).

Now you can easily see your dive lists and details, quickly change those details, and in many cases even download the latest dives from your dive computer - all on a mobile device. Additionally, Subsurface-mobile lets you track GPS fixes during a dive trip and apply those to your dive list. You can also manually add new dives to a dive list, manage dive trips and much more.

Downloading from Bluetooth and Bluetooth LE dive computers should work for all supported models (see https://subsurface-divelog.org/documentation/supported-dive-computers). Downloading from cable based dive computers is slightly more limited as it only supports download via USB serial type connections, which excludes some popular dive computers that rely on other USB connection types.

Some features included in the desktop version aren't available on mobile platforms. Most notably the dive planner, but also certain file based import and export functions. For those using the Subsurface cloud, those things can easily be done on the desktop.

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. On the flip side, this isn't a commercial product (see the "no money anywhere" part) and is instead maintained by a hand full of enthusiastic developers. If you need a product with commercial support, this may not be the right app for you.
