The more times someone picks you in a poll, the more gemstones you get (they'll be pink if a girl picks you and blue if a boy picks you). Tbh says the gems will let you unlock more questions and future features.
Tbh is only available in Florida, Washington, Texas, California, Connecticut, Massachusetts, Rhode Island, Georgia, and Indiana for now. The app isn't available for Android yet, but it's free to download from the App Store.
Despite only being in nine states, app analyst firm Sensor Tower estimates tbh has been installed more than 700,000 times as of September, and app analyst firm Apptopia estimates tbh has 46,000 daily active users.
