Deepblu Cosmiq Companion

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.

CosmiQ Companion is an unofficial app and is not affiliated with Deepblu, Inc.
Dive safe — always verify settings on the device and carry a backup.
