Average balance of a user
Add a stat which shows a user's average balance. This will actually imply monetary behaviour of a user over a period of time (and hence his generosity or lack of it). It's an easy to implement and yet cool feature.
Interesting idea! We definitely like encouraging people to be responsible about paying each other back :) We’ve also considered a graph of your total balance over time, which would accomplish some similar things. We’re a bit tied up with Android work at the moment, but I’ll add this to our list of possible future improvements.
