What it's like to use Facebook's new Snapchat competitor that's only for high schoolers

Facebook has a new app that's for teens only.

The app, which is called Lifestage, was quietly released last Friday afternoon in the App Store. It was designed by 19-year-old Facebook employee Michael Sayman and looks eerily similar to Snapchat at first glance.

Both Snapchat and Lifestage open to a camera and encourage you to take goofy videos, but the main difference with Lifestage is that it's centered entirely around high schools. You have to join a school to see videos from classmates, and there's no way to directly message someone.

Lifestage is designed for young people to "show others who they are and to find out more about the people in their school community as well as meet new people," according to Sayman, who joined Facebook immediately after graduating high school two years ago.

Even though I'm not technically young enough to use Lifestage (the app blocks you from joining a school if say you're older than 21), I decided to give it a try by pretending to be younger.
