Meta's Muse Hits 500K Users in One Week and Tops on Both App Stores

Meta's new personal AI agent, Muse, crossed 500,000 users within its first week, according to internal company data — an early signal of traction for what Meta is positioning as its flagship personalized-assistant product.

A fast climb up the charts

Independent data backs up Meta's internal numbers. Sensor Tower reported more than 902,000 standalone app downloads in Muse's first six days on the market. That pace continued: by two weeks after launch, Muse had surpassed 2.5 million downloads and was leading U.S. app download charts outright. As of Monday, the app ranked No. 1 among free apps in both the U.S. Apple App Store and Google Play.

Why the early numbers matter

Download and user-count milestones are an early, imperfect signal — they say nothing yet about retention or how often people actually use Muse once installed. But the velocity is notable: crossing half a million users in a week and topping both major app stores within two weeks puts Muse's launch trajectory in rare company for a consumer AI product, and it's a big part of why Wall Street has started paying closer attention to what Muse could mean for Meta's business.
