Thanks Jon! When I get some free time I might play with the API a little bit. I'm sure flat interest % for balance at the end of the month (or any other point in time) would be fairly simple but I would want to take it a step further. I would like it have a "grace period" of X months (or X time intervals) from money lend date before interest kicks in and even then you would only be charged interest on money that hadn't been paid in X time intervals not all you owe. Of course this would be much more difficult than a simple:

    $interestBillAmount = $amountOwed*$interestRate

That ran each month. Anyways keep up the great work, I use Splitwise all the time and it's a huge time and stress saver!
