They have a nice user interface and it seems pretty intuitive to me. This will be a great product but they need to eliminate some more bugs first. App crashed on my iPhone. Changing display settings doesnt work consistently. Interpreting receipts is pretty strong given the poor quality of some printed receipts. I would also like a way to split, prorate or otherwise itemize a receipt? I like the app but it wont be worth a subscription until some bugs are cleaned up imho.
