A social app that once felt like the whole internet moving at once now looks quieter every month, even as its signup counter keeps climbing.
Millions of accounts still exist on paper, yet fewer and fewer of them open the app on a given day.
Meanwhile, a rival built inside a much larger company is pulling further ahead.
The gap between the two says something about what actually keeps a social platform alive.
Why registered accounts and real daily use have split apart
The platform in question is Bluesky, and the split between its two main numbers explains the whole story. One number is registered accounts, which simply counts everyone who ever signed up and never shrinks on its own. The other is active monthly use, a measure of who still opens the app, and that number behaves completely differently.
Signing up takes seconds and costs nothing, so a wave of curious newcomers can inflate the registered total permanently, even if most of them never return. Bluesky was one of the bigger beneficiaries of the exodus from Elon Musk’s X in November 2024, following the U.S. elections , and that rush created a permanent spike in signups the app has never had to give back.
Daily habits are a separate contest, though, fought one notification at a time.
Once the political urgency faded, there was no fresh reason pulling the same people back in every day, and usage simply drifted toward whoever actually liked the product underneath the moment.
The scene inside two very different growth curves
Picture the two apps side by side right now. Bluesky gained roughly 10 million registered users in about two months during the post election surge, with quarterly average around 22.1 million monthly active users in the fourth quarter of 2024 . That was the high point, the moment the app looked like a genuine contender.
Since then the climb has reversed almost completely. Bluesky’s mobile app had 10.4 million monthly active users worldwide in June 2026, down 27.2% year-over-year. In addition, mobile daily active users continued to decline, falling 25.6% year-over-year in July to around 3 million , a steep yearly decline. So the app that briefly looked like a Twitter killer is now running at roughly half its former audience, having lost more than half its monthly active users from its late-2024 high .
Threads tells the opposite story over the identical stretch of time.
Meta’s Threads platform saw daily active users were down around 3% year-over-year in June, and X’s mobile daily active users dropped 7% in July to 123.7 million . Wait, that describes X. Threads itself saw daily active users climb by more than a fifth, reaching 147 million in July. That is not a modest edge; it is a platform built inside an existing social empire pulling further away from a standalone challenger with every passing month.
Even X, the app everyone expected both rivals to be chasing, barely moved, with X’s worldwide monthly active users on mobile down around 3% year-over-year in June, and X’s mobile daily active users dropped 7% in July to 123.7 million . That makes Threads the clear winner of the whole stretch, not just against Bluesky but against the platform it was built to compete with.
Where these numbers actually come from
None of this is guesswork or a company’s own marketing claim. The figures trace back to reporting from TechCrunch, which cited data from digital intelligence provider Similarweb for both the Bluesky decline and the Threads surge. That is an independent third party tracking app usage across the industry, not a figure either company chose to publish itself.
Bluesky itself only confirms the registered account total, not daily or monthly use.
The company does not publish how many people actually use it, showing only the number of registered accounts, which Bluesky itself doesn’t publish how many people actually use it. It shows the number of registered accounts, which TechCrunch put at nearly 46 million . That gap between what a company volunteers and what outside measurement finds is itself a signal worth noticing.
One detail softens the bad news slightly for Bluesky. Its smaller community remains relatively active, with a stickiness rate, the ratio of daily to monthly active users, of roughly 29% in June 2026, about the same as Threads . The people who stayed are checking in with similar regularity to Threads’ far larger crowd, just across a much smaller pool of names.
Where the comparison gets complicated
It would be easy to read this as one app simply winning and another simply losing, but the people running Bluesky are not framing it that way. Under CEO Toni Schneider, the company has publicly reframed its priority around growing the protocol rather than the flagship app alone.
The priority is now the underlying AT Protocol, the open standard intended to power a wider ecosystem of independent social apps, services and communities. That is a deliberate bet that the open plumbing beneath the app matters more than the app’s own download count.
So Bluesky now points to other software built on its network rather than its own storefront.
On the AT Protocol, the video-focused app Skylight has garnered early traction, while projects such as BlackSky and Eurosky are also growing. If any of those spin offs catch on the way Threads did inside Meta’s ecosystem, the comparison could look different within a year.
Even the reason behind Threads’ rise is not fully settled, and it remains unclear whether Threads is simply absorbing Bluesky’s disengaged users or has attracted a wholly new audience entirely. Threads saw DAU surge 21.3% year-over-year to 147 million, while website visits jumped 112% to 471.6 million, suggesting a potential user exodus from both Bluesky and X toward Threads. That uncertainty matters, since it means the shift may not be a straight swap of one app’s users for another’s.
What this shift means going forward
The lesson here is not that decentralized social networks are doomed, but that a protest surge and a sustainable product are two very different achievements. Bluesky proved it could absorb millions of new signups in weeks; it has not yet proven it can keep them opening the app months later.
That same distinction between flashy adoption numbers and quiet daily habit shows up elsewhere in consumer tech too.
It appears in how productivity suites get bundled into new AI apps, as when a major software maker built office tools into a chat assistant, and in how companies quietly extend free trials rather than announce price changes, the way one phone maker has handled its own satellite messaging perk.
Bluesky is now testing new features, including AI powered tools and private data options, to try to reignite daily use rather than just registrations. Bluesky is currently working on Attie, an AI-powered research tool, and adding support for private data, aiming to attract new user segments. Whether that effort narrows the gap with Threads, or Threads simply keeps compounding its lead, will likely show up in the usage numbers long before either company says so out loud.
