This application makes it easy to keep track of payments you owe or you have requested to your contacts. You can create a bill and send payments to any of your contacts. When they use this app, they will automatically see the requested payments and can mark it as paid.
You can request, refuse, delete or mark a payment as paid. A history view lists all the activities of you and your friends whom the payments have requested. You can also block the users from your contact list so you won't see any payments that they have requested.
Changing the currency is also possible, however it is only used for display - no conversions.
