Meta has officially debuted its Twitter-like messaging app Threads, which the company is pitching as Instagram’s “text-based conversation app.”

Mark Zuckerberg, Meta’s CEO and co-founder, announced the debut of Threads on Wednesday, marking the official release of the social networking giant’s new text-focused messaging app. Threads represents Meta’s attempt to capture the wave of users who have left Twitter amid the often unpredictable ownership of Tesla and SpaceX CEO Elon Musk.

The Threads app is now available to download for free on the Apple App Store and Google Play online store in over 100 countries, Meta said in a blog post. Threads shares Twitter’s visual aesthetic as a text-based social messaging app in which users can post short messages that others can like, share, and comment upon, according to screenshots of Threads that are available on Apple’s App Store.

People will be able to follow the same Threads accounts that they follow on Instagram and reply to other public posts in a way akin to how people use Twitter.

Zuckerberg said Threads had crossed 5 million sign ups within the first four hours.

The official release comes after Instagram released on Monday a pre-order for Threads on the Apple App Store, which said that at the time that the app was expected to debut on July 6. Many Instagram users were also recently able to obtain invitations to access Threads from within their Instagram accounts.

Although Threads is linked to Instagram, with users able to use their existing Instagram usernames, the messaging service is a separate app that people will need to download.
