Great app, makes it easy to install any app through email. Useful if you have an apk saved to your computer and with a simple email you can have it on you phone, No wires needed to transfer 3rd party apps to your phone. Great app and would recommend it if you are a beta tester or a dev and need to get apps from the internet to testing phones. The typical user can use this as a from of installed backed-up apps from a computer easily whether its on a new phone, new rom, or just need to restore your phone. Best part is this app is free.
