Appapella - The Pocket-Size Production Studio

New app called Appapella, it allows people to sing and rap over instrumentals you can then add a audio filter, similar to how you would add a photo filter on Instagram, then instantly share the recording via Twitter, Soundcloud, SMS, Email or Facebook.

Here is a example of a user using it and instantly tweeting their produced track on twitter.
