"Pay to Buddy" is Android application that was created to simplify money sharing between friends. Be it a ski vacation you took with your buddies or just a simple outing, "Pay to Buddy" will help you to share all expenses equally and fairly.The application is very easy to use. You or one of your friends will need to create an event and include everybody who participated in it and how much they spent. After event is created, your friends will be able to see it on their phones along with the details of how much they owe and to whom. Note that only event organizer can make changes to the event. Other people can only make a payment.Before everyone can pay their share for a particular event, the event has to be locked by event organizer. After that, the event is considered finalized and available for payments. Note that locked events cannot be modified. If event organizer needs to make some changes to the event, it has to be unlocked first. But remember, if somebody has already paid, the event cannot be unlocked and therefore modified.So, the only work that needs to be done is entering event details by event organizer. The program automatically calculates how much everyone needs to pay and to whom, taking into account an amount anyone has already spent. Everyone else just opens the event on their phone and clicks "Send money" button. A payment will be made to those who already spent their money.
