There are simpler apps that are better

There are other apps for video editing that work just as well as this one. However If you want to be able to add music to a video without getting it from iTunes, iMovie is handy. But thats the only great thing about it. You must keep the photos/video you have created from IMovie on your camera roll as well or it will be permanently lost, because iMovie does not actually save it. This seems like a major problem, as Ive read the reviews and others have had similar experiences where they spent hours on a project only for it to be deleted. So be careful. All in all Id say its mediocre.
