Clubhouse audio application android availability

Clubhouse mentioned Android apps in their last blog post in January 2021.

The post is essentially an important announcement from the company that it has committed to opening the app to “the world” in 2021.

But Google users should see this change soon: Obviously, that’s not the release date.

In fact, it’s not even the start date for development. What we do know is that so far Clubhouse is specific to iOS, and the company has announced that it will start developing its Android apps. This can mean that it will come out several months or even years later. We just don’t know that.
