For now, the Clubhouse app is only available for iOS. And you can register in it by invitation. The Russian developer said that he was not ready to wait for the release of the official Android client, so he wrote his own.
Now he writes that Clubhouse has started banning accounts created through the Android app. The app notifies users that their account has been blocked for “violating the spam policy.” The developer says he does not know the reason for the locks, but he has an assumption that they only affect Android users.
Clubhouse recently hired a developer to create the official Android social network app.
