Extremely useful and easy
We used this program to track expenses for a ten-day trip with friends around Europe. It made things so easy, we never really had to worry about who picked up the tab. I highly recommend it.
Two small things that would make the program even better:
1) The ability to take snapshots of receipts, for even better record keeping
2) The ability to back up data to iCloud or some other service, just in case you lose your iPhone on the last day of a long trip!
Anyway, great program.
