Apps and services for splitting and tracking bills and expenses between friends
I'd like to start using a bill/expense splitting service, like splitwise, to request payment and track shared expenses between friends and housemates.
Would really appreciate opinions on what services/apps I should consider (so far I have only really looked at splitwise)
In my mind, a good option would
a) be cross platform - at least web, iOS, and Android (Windows Phone would be a bonus)
b) have pay through paypal (or some other electronic payment system) integrated into the app.
Therefore a comment on whether these features are present would be really helpful.
