This could enable a group of friends to build up fairly long-running tabs with no effort, then pay whenever the tab hits a convenient amount. Less friction, more fun. I hope you guys succeed.
Currently, even in a group of friends where we basically always split everything down the middle to keep it simple, not even having to do a split at all until a later, convenient time would be fantastic.
Maybe this would be good in some circles, but for my friends overkill. Just need X/N, with a simple option to pre-assign a portion of the bill to the one guy at the table who drinks 2x everyone else.
