User reviews

Absolute garbage

Looks like was developed in ‘95 and extremely buggy. I can’t imagine why anyone would use this

Awesome free dive log

For a free dive log app this thing is pretty sweet! The UI is not the prettiest thing you’ll ever see, but what matters is the data and content - and this app does all of that well!
I first download the Mac app on my MacBook and I find that it’s easier for me to upload all my dives directly to my MacBook first, and then sync them with the cloud. Once you do that they all become visible here in the mobile app for easy viewing and editing.
I hope the developers keep this app current because it’s great!

Don’t

Wanted to make it work but wasted too much time. Randomly changed dive dates of all dives. Manually corrected only to have them changed again. No support. Not ready for prime time. Look elsewhere.

The most convoluted, frustrating app I’ve ever used

Seems there’s no really good apps to log dives, you’d be better off using a toaster to log your dives than this app. I’ve tried to log the same dive 3 times the exact same way and each time it gets the details wrong in a completely different way. It will just change the time, depth, duration, weight etc for no reason by a little bit of a lot. It’s like it’s a prank app.

UI is uhh quite outdated and clunky but there is a dark mode option
