Saving issues... – ICONA - Logo Maker Review

I really like this app, it’s simple, minimalistic and I can pretty much do with what I want inside the app. I’m having problems with saving my icons to my iPhone. I can email myself, but I can’t save to my phone. The app quits itself. I’m not sure if this is an app problem or a problem with my device, but I have no issues with my other apps that I use. Please fix.
