A lot or a little?
Parents need to know that Clubhouse: Drop-in audio chat is a voice-only chat-based app. At the time of review, new users need to receive an invite from a current user or join a waitlist. There are quite a few celebrities using the app, which will likely draw younger users, and there are sometimes big names like Elon Musk who attract lots of listeners. Users can drop in and out of "rooms" that are usually focused on a particular topic without drawing attention to themselves. There are moderators who can mute and remove people from a group. However, because the app is intended for adults, the conversations are often very mature, including sexually explicit language, all manner of swearing, and discussion of substance use. Profile pictures also sometimes feature scantily clad people. The adult-focused content can also be also tame, like the rooms about networking or growing a business. Users can start rooms and lock them so random users can't drop in.
