If you've tried as many apps and games as we have, you've probably come across one or two that were great... with the exception of annoying, vaguely spammy notification alerts. Starting with Jelly Bean 4.1, there's a simple and somewhat obscure solution: check the App Info menu to disable notifications. But that can get tedious, especially if you're setting up a new device. Developer Giorgi Dalakishvii has created a more elegant solution, which puts notification settings for all your apps in one handy place.
Notifications Off is a simple app, but it does a lot with a little.
