Have you ever wanted to make one app stop rotating without constantly toggling auto rotate in settings? If you have notification toggles, that makes the issue better, but not ideal. What you need is PerApp. It lets you toggle orientation lock, volume boost, and screen timeout length individually for each app. And if you have root, you can also adjust min/max CPU speed, just in case some apps need a good CPU boost.
The creator of this app knew that other apps do this, but they’re all fairly complicated. He set out to make an app that is simple and functional. You just select an app, and choose settings from a menu. It’s a great concept, and I respect his goal. I’m going to use this app, will you? Tell us in the comments if you think this is useful!
