Scuba Dive Log & Apnea: Divey

Divey is a private dive logbook and breath-hold trainer built to help you record every dive, understand your diving, and get better in the water — without ever giving up
your data.

Your dives, your data — and yours alone.

Private by design
No account, no login, no sign-up — just open the app and start
All your data is stored locally on your device by default
No analytics, no tracking, no ads, no third-party data collection
Optional iCloud sync runs through your own private iCloud, never our servers
