What is Splitwise?

Splitwise is a Providence, RI based company that makes it easy to split bills with friends and family. We organize all your shared expenses and IOUs in one place, so that everyone can see who they owe. Whether you are sharing a ski vacation, splitting rent with roommates, or owe someone for lunch, Splitwise makes life easier. We store data “in the cloud,” so that you can access it anywhere: on iPhone, Android, or on your computer.

We focus on fairness

Most people want to be fair to each other, but sometimes they forget, or can’t decide on what fair is. In addition to helping people honor their debts, we provide mediation advice about fairness issues through our “fairness calculators.” These calculators turn our crowdsourced data into a neutral fairness opinion about your personal situation.
