Simple, functional, perfect for tracking $$

I was surprised to find quite a few apps that track lending - really all I wanted was a simple way to figure out who owes me money from our weekly poker game and to avoid the whole "what!?! I dont remember that!". So I wanted to see history by person with a simple tag like poker @ stans. This was the ONLY app I found that does this. My one request would be a quick "mark as paid" option for rapid entry on existing debts. By the way, was very impressed to get a personal response within 24hrs from the developer regarding a simple question I had with the app.
