The application is designed to share spendings in groups of people or events, for example a journey. If several people fly on a joint trip, each of the participants contributes their costs and notes the members of the group who are involved in this cost. Then the application considers the balance of each of the participants, taking into account all mutual costs. The application allows you to return a debt with the minimum number of transactions or understand how much you need to make a purchase to offset your debt.
