Group + Pay = groupay! groupay is an application that makes it easy to adjust for split bill of group travel, BBQs, and other events. For example, have you ever experienced the following when traveling in a group? Mr./Ms. A: paid accommodation expenses Mr./Ms. B: paid rental car and highway expenses Mr./Ms. C: paid the entrance expenses Mr./Ms. D: paid meals expenses Mr./Ms. E: paid gasoline expenses When members are advancing various payments like this, it is difficult to calculate who should pay how much to whom when the final settlement is made... In such a case, groupay makes it easy to know "who should pay whom and how much" in the final settlement by simply inputting "who paid how much". Also, Mr./Ms. A came from far away, so I want to reduce his payment. Mr./Ms. B is a midway participant, so I want to give him a discount. A reduction function is also provided for such cases. Furthermore, you may want to split the cost of alcohol with only those who drink. In such a case, I have also included a function that allows you to select a member for each payment. Let's use groupay to free yourself from the hassle of complicated calculations when settling your account! *Depending on the amount of payment and the number of people, there may be a small error if the amount per person or the settlement amount is not exactly divisible by the amount of payment or the number of people. Please understand. URL scheme groupay://
