Bubbletrail is a free, open-source dive log for recording and organising your scuba dives.

Whether you're a recreational diver or into technical diving with multiple gas mixes, Bubbletrail keeps your dive history in one place. The app aims for a modern, intuitive interface and surfaces best-practice metrics like surface gradient factors (SurfGF) to help you understand your dives better.
