Here’s a brief refresher: Earlier this summer, contact-sharing app Knock Knock — backed by celebrity investors Richard Branson, will.i.am and Sophia Bush — offered the opportunity for people to connect by knocking on their phone screens to swap contact info.
In an update, Knock Knock 2.0 now integrates more group chatting functionality by letting you not only look for nearby friends but mutual friends as well. This lets you know more info about the people around you, which Knock Knock bills as a ‘Shazam for People’ – stalkery as that may potentially be.

The app, aimed at the college crowd, allow students to find friends to, say, start a study group or prep a party squad. If you’d like to include friends not on Knock Knock into group conversations on the app, you can also ‘@ mention’ a contact to bring them into the particular talk.
