The website is good. I have used it for years. It is a great resource. However, I don't know what has happened to the app, but it is horrible. I paid for the ad-free service, but the app is slow, has ads, and there is no way to close it once you open it. If that gets fixed, I will give it a 5.

If you have a PRO subscription on studystack.com, once you log in, the advertisements will go away. You can close the app the same way you close other Android apps by swiping up slowly from the bottom edge of the screen, then swiping the apps that you want to close.
