Apple has granted a rare exception to its strict App Store rules, allowing Twitter to rebrand as X and become the first one-character iPhone app.

Two days ago, Bleeping Computer reported that Apple had rejected Twitter's attempt to update its app name to simply X due to minimum character requirements. As a result, the app was temporarily listed in its App Store as Twitter—alongside the X logo and the X tagline "Blaze your glory." This potentially further confused users over what to call the app during Elon Musk's sloppy rollout of Twitter's new branding.
