About this app

Who paid for dinner? How much do they owe you from the trip? Stop chasing your friends and doing sums in your notes app. KoinShare is the group expense-splitting app that works out who owes whom for you, instantly and without arguments.

Create a group in seconds, invite everyone with a QR code and let each person log what they pay. KoinShare splits every expense (equally or by percentage), calculates the balances and suggests the smallest number of payments to settle the group's accounts.
