Clubhouse is a new social media app with a difference. It does not work in the same way that the major social platforms like Facebook, Instagram, Twitter and LinkedIn do. It is an audio only platform and the experts call it a social audio platform.The Clubhouse app has seen remarkable growth over the first year of its existence. At the moment it is an invitation only platform. You need to receive an invitation from someone to join Clubhouse. You can only use Clubhouse with a mobile device. Now there is an app for both Android and iOS but originally it was only for iOS users.
