Zap - Count on Us! app for iPhone and iPad

Zap is an easy, reliable, and stress free way to share and manage expenses with others. Use it to track expenses with friends and family and no longer worry about trying to remember who owes who what. And because each user sees the same history and balances, youll be able to avoid those awkward conversations when memories differ.

For example, your friend paid for dinner and you owe him for half the bill. Enter this amount in Zap and you can both easily view and confirm the amount. And as you enter new activity, Zap will start balancing all on its own, allowing you to see your net balances at a glance.
