Billy

Billy is a hassle-free, ad-free app to keep track of shared bills and group expenses. Perfect for group trips, the app visually suggests who should pay next, in order to keep the balance gap small.

Create an event, add people (supports couples and custom weights) and you're good to go !

Add a new operation in seconds. You can modify previous operations or add new participants at any time. The "settle" button shows simplified debts, and lets you track repayments. You can also share a complete report to your friends (with operations details as CSV data).

What makes Billy different? It's fast and easy to use. Adding an operation to the current event should not take more than 10 seconds. Billy is my attempt at making this simple task as smooth as possible.

Developped as an HTML5 webapp. Works offline. No shady permissions. No ads.

Oh, and yeah, it's free :)

Note: storage access is required for the app to generate the .csv data file that gets attached when sharing the results via email (also works with Drive).
