Splitwise takes the trouble out of sharing expenses – with friends, with roommates, with anyone.

We do the math for you

Splitwise keeps a running total over time, so you can pay each other back in one big payment, instead of a bunch of small ones.

Friendly email reminders

Get notified when the rent check is due…or get a reminder when you forget to pay someone back.
