DivePlot

You have a good photograph of the dive, and you have the data from your dive computer. DivePlot lays one over the other.

The app reads a dive straight from your dive computer over Bluetooth and turns it into an overlay: your depth profile as a graph, live readouts like a dive computer, or both — on top of your own photo, or as a transparent PNG for your editor.

How it works

1. Connect your dive computer and pick one of your recent dives.
2. Style the overlay: lines, colours, thickness, text fields and a legend.
3. Export to your photo album or share it directly.

What you can set

Depth, temperature, deco, pO₂ and tank pressure toggle independently, each with its own colour. In dive computer mode you replay the dive with live readouts, and you can scrub to any moment.

Your own photo goes in as the background, with zoom, pan, dim and blur. Below the depth line you can darken, desaturate or blur. Text fields for depth, duration, date, time and your name drag to wherever you want them.

Export in 16:9, 4:3, 9:16, 3:4, 1:1 and 4:5. Designs you like are saved for the next dive.

Which dive computers

DivePlot connects to the Halcyon Symbios — both the handset and the HUD — and downloads your recent dives, including rebreather data such as cell pO₂ and tank pressure. Support for more brands is in development.

No account, no ads, no tracking. Your dives stay on your device.

The free version adds a small watermark; a one-time purchase removes it.
