I've been a Splitwise user for a long time (sometimes paying, sometimes not), and have been rather frustrated at their new-ish policy of only allowing N (small) expenses to be submitted per day. And I was curious to write some Rust and thought the expense simplification algorithm would be fun to implement, so I built this.
Thought others might find it fun or useful! It's dead simple to self host if you want to try it out :)
