Muse AI App Surges Past 3.4 Million Downloads After Meta Connect Boost
Muse is quickly becoming one of the most talked-about AI apps in North America. After launching on September 8, the app has seen a sharp rise in downloads, helped by strong early reviews, Meta’s promotional push, and new feature announcements revealed during the company’s annual developer conference.
According to recent estimates from market intelligence firm Sensor Tower, Muse has now reached more than 3.4 million downloads. Earlier in the week, the app had already passed 2.5 million installs, showing how quickly interest is accelerating.
The latest figures are based on estimates available as of Thursday, meaning they may not fully reflect the most recent wave of downloads following Meta Connect. That event gave Muse a major visibility boost as Meta outlined several upcoming features designed to make the app more useful, interactive, and competitive in the fast-growing AI assistant market.
Among the features announced were video chat with the Muse avatar, support for computer use on Mac, a dedicated email address, expanded partner integrations, new connectors, and future smart glasses support. These additions suggest Meta wants Muse to become more than a simple chatbot. The company appears to be positioning it as a full AI companion that can assist users across apps, devices, and daily tasks.
Other market intelligence firms also show strong demand for Muse, although their estimates differ. Apptopia estimates that Muse has reached around 4.3 million downloads so far, with approximately 2.6 million coming from iOS. Another firm, Appfigures, estimates about 2.3 million installs as of Thursday, with downloads split almost evenly between iOS and Android.
Muse is currently available only in the United States and Canada, making its early download numbers even more notable. If Meta expands availability to more regions, the app could see another major surge.
Sensor Tower also reported that Muse’s daily active users climbed 27% on Wednesday after Meta Connect wrapped up. That jump suggests the conference did more than create temporary buzz. It helped push more users to open and try the app.
Even before the developer event, Muse was already off to a strong start. Sensor Tower estimates that the app reached 2.8 million downloads in its first two weeks on app stores. From September 8 to September 17, Muse averaged 55% day-over-day download growth.
That pace puts Muse ahead of some major AI app launches. For comparison, ChatGPT averaged 24% day-over-day download growth during its first 10 days after launch. Other AI apps, including Claude and Grok, reportedly saw download growth decline during their launch periods.
Muse has also performed strongly in app store rankings. On September 18, it reached the No. 1 spot on the U.S. App Store and has held that position since. A day later, on September 19, it also climbed to the top of the Google Play Store, where it remains highly ranked.
A major factor behind Muse’s rise is Meta’s ability to promote the app across its existing platforms. The company has access to massive audiences through Facebook and Instagram, giving it a powerful advantage when introducing new apps to users.
Meta used a similar cross-platform strategy to grow Instagram Threads, which has since reached more than 500 million monthly active users. With Muse, however, the marketing strategy appears to be more personalized. Instead of simply encouraging users to join another social platform, Meta can show people specific ways the AI assistant may help them based on their interests and habits.
Sensor Tower data shows that Meta began running internal ads for Muse on September 9, just one day after launch. Within 10 days, Muse became one of the most heavily promoted products across Meta’s own properties, ahead of promotions for Facebook, Instagram, and WhatsApp.
Meta has also expanded Muse advertising beyond its own platforms. The app is now being promoted through mobile ad networks and other major social platforms, including Reddit, TikTok, and YouTube.
By September 22, Muse ranked among the top 10 brands by advertising spend, according to Sensor Tower.
Still, advertising alone does not explain the app’s rapid growth. Sensor Tower noted that ads for Muse accounted for only 6% of ad impressions from launch through September 19. That suggests much of the app’s momentum is coming from organic interest, word of mouth, app store visibility, and curiosity around Meta’s latest AI product.
Muse’s early success arrives at a time when competition in the AI assistant space is intensifying. Apps like ChatGPT, Claude, and Grok have already built strong user bases, but Meta has several advantages: massive distribution, deep social platform integration, and a growing ecosystem of devices and services.
If Muse continues to improve and delivers on features like video chat, Mac support, email functionality, smart glasses integration, and third-party connectors, it could become one of the most important consumer AI apps in the market.
For now, the numbers point to a strong debut. Muse has topped app store charts, gained millions of downloads in just weeks, and received a major promotional boost from one of the world’s largest technology companies. The next challenge will be turning early curiosity into long-term daily use.
