Description:

Shared Expenses allows you manage the shared expenses of an arbitary number of events, and to quickly resolve how to split the expenses for an event.
The expenses from an arbitrary amount of receipts, can be split among an arbitrary number of people conviniently picked from the Contacts list, or entered manually. Optionally people can be exempted from an receipt, if the person should not share the cost.
The resolution of who owes who, and what amount, to share the expenses even is one tap away. And the resolution can be e-mailed to the participants with a single tap more.
