User reviews

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.

Suunto ocean

Not compatible with Suunto ocean still..
UI is uhh quite outdated and clunky but there is a dark mode option

Best dive logger hands down

I use this on my MacBook and iPhone and find it preferable to the SSI and Shearwater apps.

Most versatile Dive log

I have used Subsurface for years and it has every feature I would ever need. I can’t specify what is the best feature because it has many. The top 2 are first it’s compatible with most dive computers and second it works on most pc OS and mobile devices.
