You Need This.

This is BY FAR the best app I have come across for the iPhone, in SO MANY ways!!! For one, it is an app that actually increased productivity, rather than just being a distraction, and second, IT HAS EVERY FEATURE YOU COULD WANT! As a filmmaker I have absolutely fallen in love with this app. One of the many truly helpful filmmaking apps for iOS.
