Bluesky’s mobile app is shrinking. Similarweb data puts the social network’s worldwide mobile actives at 10.4 million in June 2026, a 27.2 percent year-over-year decline, with daily actives down 25.6 percent in July to roughly 3 million. Set against the boom that followed the November 2024 wave of users fleeing X, the slide looks worse. The app averaged about 22.1 million monthly actives during the final three months of 2024; by the April-to-June period of 2026 that average had fallen to 10.7 million, a drop of roughly 52 percent.
The decline is happening even as Bluesky’s registered accounts continue to grow, to nearly 46 million according to the company’s public statistics. Bluesky does not publish its own daily or monthly active usage figures, so the gap between accounts created and accounts actually used has widened. What engagement remains is comparatively strong: the app’s stickiness rate, the ratio of daily to monthly active users, was around 29 percent in June, roughly in line with Meta’s Threads.
Bluesky’s leadership sees the numbers as less alarming than they look. Toni Schneider, who dropped the interim label and became full-time chief executive in July, has redirected the company’s focus from making the flagship app succeed to making the AT Protocol the substrate for a growing number of social applications. Projects in that ecosystem include BlackSky and Eurosky, Skylight, a video-focused AT Proto app that reached 380,000 users after the TikTok deal was finalized in January, and Attie, an AI-powered research tool that expanded into an open social research tool in July. The company is also working on support for private data, a feature that could attract users more interested in private communities than in the public timeline.
The competitive picture explains some of the pressure. The data gives no sign that Bluesky’s departing users went back to X: worldwide mobile actives on X slipped about 3 percent from a year earlier in June, while July mobile daily actives came in at 123.7 million after a 7 percent drop, even as web traffic grew. The platform that appears to be absorbing displaced users is Threads. Meta’s app reached 147 million daily actives in July, up 21.3 percent from the year before, and its website visits rose 112 percent to 471.6 million. Whether Threads is siphoning Bluesky’s users or signing up people who had never joined a microblogging network in the first place is not clear from the data.
For Bluesky, the bet is that the app’s decline does not matter as long as the protocol’s ecosystem grows. That strategy carries risk: AT Proto’s other apps remain small, and the revenue and attention that sustain the company still flow through the flagship app. The private data work, if it ships, would be the first meaningful test of whether Bluesky can serve a different kind of user than the one it courted during the 2024 migration wave.
