Checked the app out, I see alot of potential for it. If you can, I'd recomend that you do a scan of the receipts so that the resolution of the picture won't be affected for really long receipts that require you to take picture of the receipt far away. Also, the app should be able to scan, pick up 1) date of transaction and 2) name of the store without requiring me to enter them. Not sure how hard something like this would be for you to program.
