Deepblu Cosmiq Companion

When Deepblu shut down, every COSMIQ+ lost its companion app. CosmiQ Companion brings it back

Your dive computer deserved better than a dead server When Deepblu shut down, every COSMIQ+ lost its companion app. CosmiQ Companion brings it back — as a native iPhone app that talks straight to the dive computer over Bluetooth. No account, no cloud service that can disappear, no strings attached.

Everything the official app did — and more Full device control: nitrox mix, PPO₂, safety factor, depth & time alarms, freedive alarms, units, backlight, screen timeout, altitude/salinity mode, clock sync. Dive log download: pull your dives off the computer with depth and temperature profiles, shown as beautiful charts. A real logbook: name your dives, tag the dive site on a map, add notes, fix the date if the computer’s clock drifted. Your data is portable: export CSV or UDDF and import into Subsurface, MacDive or divelogs.de anytime. Survives everything: the logbook lives in your private iCloud Drive, so it follows you to your next iPhone. Open source, community powered Built on the community reverse-engineering of the COSMIQ protocol: cosmiq5-web and libdivecomputer. The app’s own source is at github.com/pbouffaut/cosmiq-ios.
