Bored of trying to find that missing change coin?
Try Top Billin, the one and only app that calculates the exact amount of money each person would need to pay in a group payment. This would be the case of friends going out together to dinner, a cinema, etc. It usually happens that we pay in group but everyone wants to pay his part. It also happens that no one has exact change. The app asks for each individual taking part in the payment to input the money he has, introducing the exact coins and bills, and the amount of money to pay, adding it to the amount of money they have to pay altogether.
The app calculates what coins and bills each one has to give to the other individuals, and to whom they have to pay. The idea is for users not to have to think of the best way they could be even with payments, especially in big groups. In case there is no exact change, it minimizes the differences between users. The app is designed so it can offer money input of world-wide currency (dollars, euros, yens, etc), but for now it is only prepared for Euro and US Dollar locales. (Pound sterling also usable, although you will have to put up with Euro images for the meantime).
We will try to expand to the majority of currencies. Contact us if you want it done for yours!
