The app lets you store, archive, or delete backups by simply selecting them from the main interface. Once they're archived, you can even send the APK file by email, allowing you to easily store it on any disk drive. Of course, you can also restore any app.
The app interface is really intuitive, so regardless of how much experience you have with Android it probably won't take you more than a minute to fully understand how all its features work.
App Backup and Restore is a very useful tool that makes managing all your apps and APK files much, much easier.
Requires Android 4.0 or higher
