UNHIDE by Ray-Ban

This app allows you to find your friends in any crowded place. For example at a music festival, a crowded beach, a city park or a ski slope.

How does it work?

You upload a list of friends from Facebook, and by holding your phone on its side, you get a ‘crowd view’ and the app points out your friend, by showing his/her profile picture.

With the app, you can also poke your friend to remind him that you’re searching him.

When you found your friend in a funny or special place or situation, you can take a picture and instantly share it on Facebook.
