I second the recommendation, it works really well.

Something for F-Droid users to keep in mind: If you try to use Obtanium to update a app installed from F-Droid it will most likely fail. F-Droid does their own apk builds with their own build signatures, which means that the apks Obtanium pulls from GitHub won't work to update them. Completely uninstalling the app and reinstalling it from Obtanium has always worked for me.
