Splitwise/SplitKitty app but with sats. For example: 3 people go on a trip - person A pays for accomodation, person B pays for car fuel, person C buys groceries at the shop. The one who makes each payment inputs the costs (and unequal distribution if needed) into the app, then the app calculates who owes who and settles it with sats (or just keeps score until triggered manually). If that could be done in an app that's available within Alby Hub, that would be awesome. Alby Split? :)
