Fantastic, but with some issues.

This app is amazing, except it has a major bug. The app allows you to make amazing, realistic effects, which is awesome, but it doesnt let you save your videos to anywhere else but the app.

There is an export button for you to save videos to your camera roll, but it doesnt work. Even after enabling the Photo Sharing in the Settings.

The app has two ways to view the video while editing. Frame view and Time view. Frame view slows it down frame by frame to get the effects perfect, while time view allows you to watch it normally.

Time view, however, doesnt work and is a worse, laggy version of the Frame View.

Just know that when you download this app you will be faced with those issues, and the occasional crash if you try to push buttons too fast.
