I have used Genius Scan on the iDevice and then moved over to KitKat and used it there. For android I have been using the free version (with the standard bottom banner advert) and it works fine for me. I put them in a PDF and have the app send to Dropbox (there are other options too). Then pick it up on the PC side for my Expense Report.

Worth a free download to give it a try. They have a paid version as well.
