Willio

New: uneven shares and multiple currencies support!
Willio lets you split bills between friends and keep track of who owes what.
+ Keep track of who owes what +
Create an event, and add the participants from your contacts. Then add a payment each time someone pays for the group. If the payment should not be split equally among the participants, you can specify specific shares or amounts.
+ Use multiple currencies +
Choose a currency for your event. If you have to do some payments in other currencies, just pick the one you want when adding the payment. Willio will get the exchange rate for you. If you are offline, you can set the exchange rate manually.
+ Keep it balanced +
See at a glance who should pay next, to keep the debts balanced. Willio sorts the participants by who owes the most.
+ Don't break the bank +
You have a budget and don't want to spend too much during your weekend? Willio shows the amount you spent so far.
+ Send a report via email +
Send an email listing who owes what to all the participants. The email report describes how the debts can be solved. Also the payments description is attached as a spreadsheet file.
If you have any question or suggestion about Willio, please send an email to [email protected].
