I am the other developer on this project. We worked hard on making sure the parsing was super accurate so try your worst quality receipt and let us know how it does!
This is actually very similar to our implementation. The host pays the bill then users go in and either claim an entire item or split the item between multiple people. Each person is then assigned an individual bill with quick links to pay the host!
Oh~ I missed "Shared items split cleanly" in the copy. And I didn't feel like creating a new account to check it out. Would be nice if you didn't have to sign up/login. (Maybe like how a shopping cart allows creating an account at checkout)
(And I initially thought "TabChop" would be a windows management tool: split windows...)
