Bluesky's mobile app had 10.4 million monthly active users worldwide in June 2026, down 27.2% year-over-year, according to data from digital intelligence provider Similarweb. The decentralized social network, which gained significant traction during the November 2024 exodus from Elon Musk's X following the U.S. elections, has struggled to maintain its momentum nearly two years later. The findings indicate that while Bluesky continues to add registered accounts—reaching nearly 46 million total users—fewer people are actively using its mobile app on a regular basis.
The drop in engagement extends beyond the monthly figures. Mobile daily active users fell 25.6% year-over-year in July to around 3 million, according to Similarweb's data. Even more striking, the app has shed more than half its monthly active users from its late-2024 peak, with quarterly averages declining from roughly 22.1 million monthly active users in the fourth quarter of 2024 to 10.7 million in the second quarter of 2026—a decline of approximately 52%. Among those who remained, however, the platform maintains a stickiness rate (the ratio of daily to monthly active users) of roughly 29% in June, comparable to Threads.
The data doesn't necessarily suggest that Bluesky users have migrated back to X, as some may have feared. X's worldwide monthly active users on mobile were down around 3% year-over-year in June, while X's mobile daily active users dropped 7% in July to 123.7 million, despite the platform maintaining around 302 million monthly active users as of June 2026 and growing web visits by 5.3% year-over-year in July to 4.7 billion. Instead, the report highlights Threads as the app that may warrant attention, with daily active users up 21.3% year-over-year to 147 million in July 2026, and website visits surging 112% year-over-year to 471.6 million.
For Bluesky's new CEO, Toni Schneider, these numbers may not be as troubling as they appear. The company isn't solely focused on making Bluesky (the app) succeed, but on enabling the underlying protocol (AT Proto) to power a growing number of social apps, services, and communities. That's already happening, as projects like BlackSky and Eurosky are expanding, while some AT Proto apps like the video-focused Skylight have gained early traction. Additionally, the company has launched new products, including the AI-powered research tool Attie, and is now working on adding support for private data to Bluesky—a move that could attract a different type of user more interested in private networking and communities than the public square. The company's pivot toward building infrastructure rather than a single destination app may explain why shrinking mobile usage doesn't signal failure in its leadership's eyes. Whether that strategic bet pays off depends on whether the broader ecosystem can grow faster than the flagship app is contracting.
