Intuitive interface and quick to put something together. I really like the app. Saving slideshows in different resolutions to see what is best for sharing via Dropbox. It crashed a few couple of times when Exporting to iPhone photo library. The show had over 80 photos (3 sec show, 1 sec transition, and music)... About 5 mins. I figure its because Im working on wifi with iPhone, not a computer. I still love it.. Much better than on a laptop.
