The creators of livestreaming pioneer Meerkat made a new app in secret—and it’s doing great. Houseparty is a group video chat platform designed to “capture some of the spirit of Meerkat but in a more personal way that encourages users to participate.” Users can create or join “rooms” to video chat with friends, and are warned if an unknown mutual friend joins the group. The app opens to a camera like Snapchat, is “sprinkled liberally” with emojis, and has already generated almost 1 million mostly teenage users during its testing phase. (Mashable)
