PayWho — Quick Bill Splitting for Groups Going out with friends? Someone paid for dinner, someone else grabbed the cake, and not everyone shared every item. PayWho handles exactly this — no spreadsheet needed. HOW IT WORKS Just 3 steps: 1. Add your group — enter everyone's names 2. Add the bills — set the amount, who paid, and who's splitting it 3. Hit Split Bill — PayWho calculates exactly who owes who, and how much PayWho consolidates all the individual bills into the simplest possible set of transactions. Instead of a web of payments between everyone, you get a clean list: "Ben pays Alice $46.67, Claire pays Alice $30.00" — done. PERFECT FOR - Birthday dinners & parties - Group holidays & trips - Gatherings where different people paid for different things - Any situation where you just want to settle up fast WHY PAYWHO No login required — open and go No in-app purchases — completely free Works offline — no internet needed Handles multiple bills with different payers and different participants Clears up in seconds — made for settling up on the spot The name? A nod to PayLah and PayNow — because after PayWho tells you the breakdown, you know exactly who to pay.
