Ive recently moved into an apt with two roommates and all three of us downloaded friendcash to track our expenses. It performed well tracking various fees/purchases/refunds/etc.
The feature I like the most is the ability to sync with dropbox, ensuring that were all seeing the latest numbers.
Would be five stars but it has crashed a time or two and also I once changed an email address and it removed the contacts precious records necessitating everything to be re-entered.
