Although the first few UI elements are simple and well laid out, you should be given the option to rescan and adjust the corner points before sending to Evernote. I have stopped using this app as it misinterprets corners too often and I have to go back and rescan the document and set this manually.
I love the cloud storage as it is perfect with this kind of mobile solution, but it needs to be simpler to scan in basic documents.
