A lot of people spend too much time taping receipts to 8.5" x 11" paper just to scan it and turn it in to a PDF to upload into an expense report system.
I don't know about you but I've got too much to do when I get back from a trip to have an arts and craft hour at my desk. Scanner Pro by Readdle is on sale during Christmas for $2.99. This will last until the 26th.
Either way, it will show you're far more capable than an 8 year old. It's time to start living in 2014 and create a PDF of your receipts as you make your purchases. I like both of these apps for this functionality and much more. You can't go wrong either way. Get both!
