Popular new teen app, TBH, has just been bought by Facebook. The app, which was named after the acronym ‘to be honest’, has had many teens flocking in to participate in anonymous polls.

The polls are controlled by the app creators, and the app has spread fast among teens.

The app, which is designed for people who are 13 or older, and only available on iOS for now, has reportedly been downloaded by over 5 million people in just the past few weeks.

Facebook confirmed that it had acquired the app, but did not give the details of the terms. However, the four co-creators of the app, Nikita Bier, Erik Hazzard, Kyle Zaragoza, and Nicolas Ducdodon, will reportedly join Facebook’s Menlo Park Headquarters.
