Clubhouse app: is it on Android, what is the voice-only social media network - and how do you get an invite?

With an invite-only policy, celebrity users and a market valuation of over a billion dollars less than a year after its launch, interest in Clubhouse is high.

The new social media app is currently only available to iPhone users, and even then you have to know somebody who’s already a user to get yourself in.

So what exactly is Clubhouse? And how do you get involved?
