Mytubo is a casual, fun app that lets you apply 14 toy camera effects to existing photos in the gallery or real time camera shots. You can then save the edited snap to your phone or to a mytubo account, and share it via Facebook, Twitter, Flickr, Tumblr, Email and SMS. The interface is fairly straightforward and the photo filters really do make your images eye-catching.
Requires: Android 2.1 and up
