A free app for Android, by Zeal Mobiles.

The Backup and share app is an easy-to-use app if you are wanting to save and send files to another device. Just install the app on your phone, save any application to your SD card in the backup and share app folder and you can now share it with just a single click. This app facilitates sharing by bluetooth, email, and other means. There is no need for any internet connection as it works even if the app is offline. It also works even without a root phone. Very convenient app as you can do the sharing anytime.
