I never fight with roommates over bills because of this genius expense-splitting app

The bill for brunch comes, and silence falls over the table. I've been there.

At 26, I've lived with 10 roommates at different times in my life. Splitting the bill - for brunch, utilities, rent, the movies, and everything in between - was a consistent pain point throughout these relationships.

Then I found Splitwise.

Splitwise is a free tool for friends and roommates to track bills and other shared expenses. The tool, which has been available for several years, tallies who paid what and sends reminders at the end of the month to settle debts.

Here's why I'm obsessed.
