LONDON — Meta is poised to unveil a new app that appears to mimic Twitter — a direct challenge to the social media platform owned by Elon Musk.
A listing for the app, called Threads, appeared on Apple’s App Store, indicating it would debut as early as Thursday. It is billed as a “text-based conversation app” that is linked to Instagram, with the listing teasing a Twitter-like microblogging experience.
