Share costs as a couple
Groceries, holidays, the car, the flat: couples share a lot of costs, and not always half and half.

Half and half, or not
Split equally, by a ratio that fits your incomes, say 3 to 2, or by exact amounts on a single payment.
Two taps per payment
Tap who paid, type the amount, done. The amount field does maths too, like 3*12.50.
See where the money goes
Use your own categories and see spending per day, category and payment method in the statistics.
One group for everyday life, one per holiday
Make as many groups as you need and switch between them from the group name at the top. Both phones stay in sync, Android and iPhone alike, and the web app works on a computer.
