Ratings and reviews

Downloading a card does not download. It says "downloaded" but it does not download. This needs to be fixed ASAP. Why are screenshots for app content? Why the heck is that helpful? Please add back the ability to screenshot on the android app especially if you have to get diver information from a card having this disabled means you have to manually type it. Every. Single. Time. To be clear anyone can get another phone and take a picture of the app. Blocking screenshots just makes things worse

Not intuitive. There isn't a section to view my profile or personal information. It doesn't sync with Garmin devices to easily add dive logs.

Usable but needs improvements. the elarning just opens a web view and one needs to login again, this should be native inside the app. For the divelog, it really needs some import functionality to bring in dives from other apps, like subsurface because. Manually entering 10s or 100s dives is impractical
