Facebook just announced a strange new app called Lifestage, and it was built for teens by a 19-year-old wunderkind Michael Sayman, a Facebook product manager.

This new app asks for your happy face, sad face, likes, dislikes, best friend, the way you dance and more, but instead of filling in this biography quiz with text, you shoot videos. Lifestage turns those clips you recorded into a video profile others can watch.

While technically anyone can download Lifestage, anyone 22 or older will only be able to see their own profile. That’s because it’s built for high-schoolers to learn more about their classmates. A quick swipe lets you block and report people, too, in case anyone sketchy tries to creep on the kids.

The app lets you select your school, but you won’t be able to see other users unless at least 20 people from the same school start using it.

(Facebook account is not required).

“Lifestage makes it easy and fun to share a visual profile of who you are with your school network,” Facebook said in the app description. The company also warns that everything posted to Lifestage is always public, because privacy is for chumps.
