Not 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.

One 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.

Could 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.
