Such potential but crashes – Collage Lite Review

So many great features for a free app. But if I try to use them (resizing, transparency, sepia, more than one pic) in combination, I crash. It crashes at least a couple of times every time I try to make a project. Would be 5* if the crash problem didn't exist. I just got this app in Feb and I see others have been reporting the crash problems for months but has not been fixed. Would buy the full app if I was sure it wouldn't crash but maybe free or not, the iPhone just can't handle the processing for this apps features. Maybe it's the iPhone's limitation and not the developer??? I'm not a technical expert. Hope someone will comment on this.
