Subsurface vs DivePlot

Subsurface-mobile is an iOS dive log application based on Subsurface, the best free open source dive log application available on Windows, Mac and Linux. Subsurface-mobile allows you to access your dive log on your tablet or phone, edit the data and even download new dive information from many Bluetooth LE enabled dive computers. Using a 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). To get support from the developers, please use the in-app menu entry "Ask for support" Please check out the Subsurface-mobile user manual: https://subsurface-divelog.org/documentation/subsurface-mobile-v3-user-manual (also available from within the app) 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.

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.
