Going out is fun. Divvying up the bill? That’s not quite so fun. For some reason, no matter how clever your group of diners, there’s something about a restaurant bill that makes the collective wisdom go fuzzy. With the Plates app, users can skip the back-of-the-receipt arithmetic and easily calculate what everyone owes, even with tax and tip. For parties of 10 or fewer, Plates will do the division for you — even if a dish wasn’t shared by the party. Just enter the price of all the items on your bill, let the app know who shared what and you’re all set to go.

The app is published by Splitwise, a company devoted to making it easy to split all kinds of bills with friends and family, but no Splitwise account is required to use the app. The company has said an Android version of the app is in the works. Free, for iOS devices.
