Turn your dive computer log into a beautiful photo overlay. DivePlot reads a dive straight from your dive computer over Bluetooth and turns it into a clean, professional overlay: your depth profile as a graph, live readouts like a dive computer, or both — on top of your own dive photo or as a transparent PNG for your video editor. How it works 1. Connect your dive computer and pick one of your latest dives. 2. Style your overlay: graph lines, colors, line thickness, text fields and a legend. 3. Export to your photo album or share it directly. Overlay studio • Depth, temperature, deco, pO₂ and tank pressure as graph lines — each with its own color and toggle • Dive computer mode: replay your dive with live depth, time, pO₂, temperature, CNS and tank pressure readouts • Scrub to any moment of the dive — the readouts follow • Add your own photo as background, with zoom, pan, dim and blur • Effects below the depth line: darken, grayscale or blur • Draggable text fields (depth, duration, date, time, your name) with size, color, alignment and outline • Legend, line thickness slider and multiple export formats: 16:9, 4:3, 9:16, 3:4, 1:1 and 4:5 • Save your favorite designs and reuse them on the next dive • No photo? Export a transparent PNG to use as an overlay in any video editor Supported dive computers DivePlot connects to the Halcyon Symbios (handset and HUD) over Bluetooth and downloads your most recent dives — including rebreather data such as cell pO₂ and tank pressure. Support for more brands is in the works. No account, no ads, no tracking. Your dives stay on your device. Free version adds a small "created with DivePlot app" watermark; a one-time purchase removes it.
