Let me just say that I have a lot of friends incapable of fairly splitting a check. Even when we separate the check on paper, it rarely comes out right, and I always get stuck with paying the difference. This app keeps that from happening. I used it at lunch today and was impressed by how simple and how helpful it was. Everyone paid their proper amount, and the total came out correct for the first time ever. I can only imagine how much money this app would have saved me if I had it over the last few years. Thanks for a great app that will pay for itself many times over.
