Bubbletrail is a free, open-source dive log for recording and organising your scuba dives
Bubbletrail is a free, open-source dive log for recording and organising your scuba dives. It connects directly to dive computers over Bluetooth, imports logs from Subsurface and other programs, and displays dive profiles including depth, temperature, tank pressure, and calculated deco. 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.
