App

If you can get signed in on the app it is a wonderful site. But..........
Good luck logging in!

Annoying

I guess seeing as how this was an issue 2 years ago it’s not been fixed I tried logging in 5 times kept saying not able to with that email and password I go to the actual website and it lets me log in with that exact email and password

Difficult to Use

This app constantly bounces you back-and-forth between the app and the website, asking you to sign in at every move. Adding new coins isn’t easy either as it doesn’t allow you to scan the barcode you have to manually enter the number.

Difficulty opening

I reset my password and proceeded an attempt to login and it failed 🙁

Undermines NGC’s credibility

Constantly acts like it’s been hacked into. It continually asked for you to sign in… like right after you’ve signed in and also when going from one tab to another. For example, to check submission status, it takes three logins. And then, after you’ve successfully logged in during the same session multiple times, it tells you that you need to change your password. This is behavior that security experts say indicate a site has been compromised. Oh yea, just who I want to trust my valuables with.
