Meta's new AI agent app Muse climbs to No. 2 spot in US app charts

Meta's AI agent app Muse, launched Tuesday, has been downloaded more than 83,000 times on iOS in the United States, according to data from market intelligence firm Sensor Tower. That performance has pushed the app to the No. 2 spot on the App Store's Top Charts, up from fourth place on Wednesday.

Still, Muse's debut looks modest next to other Meta app launches. Threads drew over 4.3 million US downloads on its first day, while the Meta AI app logged 108,000 downloads during its debut. Muse also trails ChatGPT's early trajectory — that app surpassed half a million US installs within less than a week of launch, averaging roughly 83,300 downloads a day, a pace Muse took twice as long to match.

On Android, Muse is performing considerably worse, ranking only No. 338 in the Productivity category on Google Play, with download figures not yet available there. The app is also accessible via the web and WhatsApp, though those channels aren't reflected in the current estimates.

Muse represents one of Meta's biggest bets yet, built on the belief that task-completing AI agents will define the next phase of consumer technology. Competition in this space is intensifying, with rivals including Google's Gemini Spark and Anthropic's Claude Cowork. A notable challenger is Instinct, a text-message-based AI agent recently valued at $2.5 billion, which this week rolled out email addresses for all users, launched a feature letting users' agents coordinate with friends' agents, and added integrations with Stripe and 1Password along with a location-sharing capability.

The timing of Muse's launch may also have played a role in its numbers. The agent, which requires users to share more personal data with Meta, debuted just days after the company agreed to an $18 billion multistate settlement over lawsuits concerning social media's harms to consumers — the latest in a long string of privacy-related legal troubles for the company.
