I should have known better than to buy an app with such a vague description, but I figured for $2 Id roll the dice. The "import/export" capabilities mentioned in the description are useless, as far as I can tell. The only file type Ive found that can be imported is .txt files, but I have never been able to get one to successfully import, getting "import general error", maybe the least helpful error code ever. The help menu has nothing about import/export, and very little about anything else.
If you want to manually type in all of your receipts, this is a great app for you. I got exactly what I paid for, a nicely designed app icon and almost no real functionality.
