Looks like a really great start! Just gave the app a quick test and the basics seem to be working fine. Apart from automatic cropping and perspective distortion correction others have mentioned already, the white margins of the exported PDFs are IMHO quite a bit too large. In fact, as the app is a document scanner, I'd not expect any border at all.
