Not bad, but UI flow needs some work I tried BillPin previously and found that their syncing simply didn't work. I use a variety of iOS, Android and PC based browsers and as I transitioned between these it sync'd incorrectly and simply messed everything up. So this is the best bill splitting app I've used so far, but the UI needs some work as it's a little confusing to start with. My biggest confusion was that the "Quick Entry" button is actually the *only* way to enter a tab/bill - there's nothing quicker about it. I was trying to enter a historical bill. This option started by requesting that I take a picture which I was not able to. So I tried to find an alternative way of entering it to no avail. Eventually I entered it on the website using the more descriptive "Tab (Itemized Bill)" button I later realised was the same as "Quick Entry" on mobile. I messed up entering some payments as I was exploring and it has created a new contact. I'm unable to delete/remove that contact. Default currency does not work (it keeps going to Euro). Anyway, I'm liking it so far... I hope you continue to develop this!
Doesn't work with 4.0 Didn't work right on my iOS 4. Couldn't change preferences and won't add up transactions
* Improved Contact List: With the new interface you can simply recognize it with a thumbs up (= you are the creditor, ie. your friend owes you money) and thumbs down (= you have to pay your friend back)
* Through the web interface it is possible to add comments and photos like additional receipts to a transaction. These are now synchronized to your mobile phone and can be viewed.
* Show progress during initial Synchronization.
