I've lived in shared housing since 2012. Living with housemates is great but messes tend to accumulate faster than they're cleaned, and for good reason. Too cheap to pay house cleaners, we experimented with chore charts on a whiteboard for years.

Eventually our whiteboard chore chart looked a lot like economist Elinor Ostrom's framework for solving the Tragedy of the Commons. It also worked! After a while we wrote software that made the chore chart operate automatically.

After using the software ourselves for over a year we're releasing it for others to use. Hopefully Choremate helps you keep your friends from becoming enemies too.
