Crashes repeatedly on 4s w/ios 7

Looks like a great app designed with smart interactions that truly take collage making to the next level.

Unfortunately, it crashes repeatedly upon rendering with my iPhone 4S running ios 7.

Ive replicated the crash with both multi-pane and 2-up images, both with and without filters. After multiple tries I have not successfully created any collages with this app.

I really like the idea behind the app and trust that the developer will squash this bug, but until then I can only give 3 stars.
