  1. 4/5Could use some improvements

    This app is great for downloading certifcation cards and the platform for elearning is very well thoughtout. Diving is more a lifestyle than simply a hobby and it would be nice to see the app reflect that. While the articles are great (but can be read on DAN) an online dive log would be more useful. A dash board with all certifications (accross all organizations) would be useful as well. The look and feel of the app is dated and could use some modernizing and controls more user friendly.

  2. 4/5One Small Issue

    The app works well and is responsive. It’s always easy to look up information on it. Issue I see with it is that you have to login every time you open the app practically.

  3. 3/5Not great but quickly improving

    The app is laggy way too often, especially when selecting dive sites. Lots of buttons on the dive log are unintuitive and take waaaay too long to press. It is getting better fairly quickly though, lots of glitches like the constant sign outs are going away. It’d be nice to see some kid of autofill for consecutive dives or dives at the same site, and a way to input courses and buddies that aren’t a part of the SDI database.

  4. 2/5You can’t log out

    Very annoying that you can’t log out of this app! My young son does not have a phone so I need to be able to log out of one account and into another to show our certificates. This app has no log out feature so you can’t do that. Even after permanently deleting the app after reinstalling it still is logged in and no option to log out and log in as a different user.

  5. 3/5Hopefully continues to improve

    Good that it has all my certs. Manually loading a dive is slow. Also wish I could see my dive notes when I click on my log details. I can only see them when I go to the edit dive page
