Genius Scan is great for scanning things into the app itself, but once its saved there you cant really do anything with it. Its incredibly frustrating. Ive had to email documents from Genius Scan (even just to my own gmail account) 5 or more times before it actually works, if it even works at all. Also the app used your default email as the "sender" but Ive had to go back into my gmail to make sure it was sent. It often just sits in your "drafts" folder and never gets sent unless you manually login to your email go to the drafts folder, open it up and click send. Again, that is only if the document even makes it to your default email. So if your needs are strictly to get a document saved and stored to your phone, its great. Anything more than that may or may not work (more often not, in my experience) and is extremely frustrating.
