what app for scanning
Genius Scan is great for scanning things into the app itself, but once it's saved there you can't really do anything with it. It's incredibly frustrating. I've 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 I've had to go back into my gmail to make sure it was sent.
