Bouncer was our pick for the best new Android app from 2018. It’s a security app with a unique premise. The app lets you grant temporary permissions to applications. So, for instance, you can let Facebook access your location long enough to check into a place, and Bouncer disables the permission once you leave Facebook. This is a great way to use all of the features of a social media app without digging into your settings to disable those permissions or giving those apps permanent access to your information. The app runs for $0.99 and should work on most (if not all) apps. It’s rumored that this could be an Android Q feature. If that’s true, then even Google really likes this app.
