Google Play's new invite-only Who's Down app allows teens to broadcast that they are "down" to hang out at a movie marathon or during a night on the town, by tapping a toggle to show they are available. If a user's friends keep ignoring them, they can invite them to categories of hangouts by selecting a Google recommendation or creating their own, and use group chat to talk about the planned night's activities. The app is now available for Android and iOS.

9to5 Google first reported the new app. It is different from Down, which was previously called Bang with Friends.

Who's Down is also very similar to Apple's Find My Friends app and others, according to Engadget. The big difference is that the Google app lets users share they are available for a certain activity.  

When people try to sign up for Who's Down, they must enter their email address and school, according to The Verge. Google has shared few details about the new app.

One big question is how the app matches users with friends. It might work with Google contacts or Hangout chatmates.

The search giant's goal could be be to draw in young consumers through messaging apps. It is already a big money-maker, but the company is far behind rivals including Facebook's Messenger and What's App.

Who's Down might be successful. If it is, then some features could be added to Google's Hangouts app.  

The new Google app is available now for download for mobile owners who are "down."
