Love it but it freezes

I love this app and its filters. I use a lot of photo apps as I take a lot of photos. This one is always the best for vignettes and black and white filters. The only problem I have is that is always freezes after saving a pic to the camera roll. You either have to restart your phone or redownload the app. Huge waste of time for me. Fix this please!
