About BubbleJournal

BubbleJournal is a dive log for every dive from every dive computer, kept together and yours to keep. It is built and run by one person, Dmitry Shalimov, in Pennsylvania, USA, with no investors and no ads.

Who writes it

I'm a recreational diver. My own dives are in BubbleJournal: more than ninety of them, recorded lately on an Oceanic Geo 4.0, among them the cenotes of the Yucatán on a trip in May and June 2026. The screenshots in the guides and on the dive computer pages are from that logbook.

What BubbleJournal promises

• Every file you import is kept exactly as uploaded, so nothing is lost if BubbleJournal learns to read more of it later.
• What the dive computer measured stays apart from what BubbleJournal calculates, and each calculated figure says how it was worked out.
• Your dives are never sold or used for ads. You can download all of them, or delete everything, whenever you like.
