A free program for Android, by ENIMA Apps.

This app assists you in creating backups for your phone apps. It does that by extracting files from the selected apps, and then creating apk files for them – which you could then save, store, or transfer to your SD card or internal storage.

You can also transfer apps by transferring apk files from an old phone to a new phone, just so you would not have to go through the entire process all over again.

Other features include: backup and restore options for apps that are not frequently used – so that you could save more space, manage or sort apps, and more.
