This is an app to split bills, similar to the Plates app by Splitwise, but a little more powerful as it allows different shares for different people on each item.
If you add a single item of 10 dollars and divide by 6 people, we end up with a -0.02 total:
Probably because we round up each share and add them all up. Instead we should just randomly assign some extra cents to a couple people and keep the total correct.
