Mideast Peace Plan

Check out this report by Omer Barak describing a new dating app called “Verona,” created by Matthew Nolan for Israelis and Palestinians:

Verona, which has the tagline “World peace, one swipe at a time,” is almost identical to Tinder – accept for the Israeli/Palestinian catch.

Users first log into Facebook and create a profile where they identify themselves as either Israeli or Palestinian. They then upload a photo of themselves and are then shown photos of people in their area who identified as the opposite group.

Users then swipe right if they like someone or left if they don’t. If the two match, if both swipe right, they can start matching and potentially meet.
