Tweet.app is the new name of Operation Bluebird’s attempted Twitter revival. The rebrand came one day after a Delaware federal judge split X Corp’s trademark case down the middle. Operation Bluebird announced the rebrand on September 4, dropping the Twitter.now name it had launched under barely a week earlier. In a memorandum opinion filed September 3, Chief Judge Colm F. Connolly barred the startup from using “Twitter” but let it keep “Tweet” and the bird logo for now.
What the judge decided
X Corp asked for a preliminary injunction covering thirteen registered marks. The court sorted them into three groups: eight Twitter-formative word marks, two registrations for “Tweet,” and three for the bird logo. On the Twitter marks, the judge found that X still makes bona fide use of the name. Its Apple App Store listing reads “Welcome to X (formerly known as Twitter),” and X added that line on purpose so people searching for Twitter would find the app. Because Bluebird’s site copied Twitter’s sky-blue look, confusion was likely, and the injunction was granted.
The Tweet mark and bird logo went the other way. Neither appears in the App Store listing or anywhere on the x.com home page. X’s own witness conceded that point at the April hearing. The judge also cited Elon Musk’s July 2023 post that X would “bid adieu to the twitter brand and, gradually, all the birds” as evidence of intent not to resume use. As a result, the court found Bluebird likely to prove that X abandoned both marks and denied that part of the motion. However, this is a preliminary ruling. The case still heads to trial, and X could yet win the bird back.
Why the startup renamed itself within a day
Operation Bluebird, Inc. is a Virginia company led by trademark attorney Michael Peroff and former Twitter lawyer Stephen Coates, according to TechCrunch. It petitioned the Patent and Trademark Office to cancel X’s Twitter and Tweet registrations on December 2, 2025. Then it launched a platform called Twitter.now in late August. The opinion notes the launch came after briefing closed, so the judge did not weigh it. Coates, the company’s president and general counsel, answered Musk’s old post directly in the release. “And now we shall bid welcome to the Tweet brand and gradually, all the birds. To us, tweet is sweet,” he said. The company’s FAQ adds that it will follow the order on the Twitter marks while the case proceeds.
What Tweet.app actually is today
For now, Tweet.app is a waitlist with a price tag rather than a working social network. The company charges $20 for early access, which reserves a handle and assigns a numbered Founder badge. A $40 tier called Fighter adds a slingshot badge. The company says the money funds both the build and the lawsuit. Operation Bluebird says more than 172,000 people requested a handle before launch. Meanwhile, its promised trust features, including a veracity engine called VERA and a user-set Trust Dial, are not live. The site says so plainly: “None of this is live yet.”
That leaves the revival in an odd spot. It has the word and the bird, at least until trial, but not the name people remember. It also faces a crowded field. Bluesky recently gave users a way to opt out of its Discover feed. At the same time, X itself keeps expanding with X Money and an encrypted XChat app. Tweet.app has won the right to a nostalgic name. Now it needs a product to attach it to.
