Meta’s new AI agent app, Muse, climbed to the No. 2 position on the US App Store as of September 10, 2026, days after its Tuesday launch — but early download figures show it trailing behind previous Meta app debuts by a significant margin.
According to market intelligence firm Sensor Tower, Muse has been downloaded more than 83,000 times on iOS in the United States, where the app is currently exclusively available. By comparison, Threads surpassed 4.3 million US downloads on its launch day, and Meta AI recorded 108,000 US downloads during its debut. ChatGPT, another benchmark, averaged roughly 83,300 daily downloads in its first week — a figure that took Muse twice as long to reach.
Muse’s performance on Android has been weaker still, ranking No. 338 in the Productivity category on Google Play. Android download numbers are not yet available. The app is also accessible via the web and WhatsApp, neither of which are reflected in these estimates.
Meta launched Muse as part of its push into agentic AI — software designed to take actions on users’ behalf. The company views this as a defining direction for consumer AI. Muse requires users to share personal information with Meta, and its launch came just days after the company agreed to an $18 billion multistate settlement over alleged social media consumer harms. Meta has also faced prior data scandals and multiple FTC fines over privacy violations.
Muse’s main competitor in the consumer agent space, according to the source, is Instinct, a text-based AI agent recently valued at $2.5 billion with $350 million in funding. Instinct has been adding features rapidly, including email addresses for users, a location-sharing capability, integrations with Stripe and 1Password, and a feature allowing users’ agents to communicate with each other to coordinate plans.
Muse’s numbers remain early, and the app has been rising through the charts — moving from No. 4 on Wednesday to No. 2 by Thursday — suggesting the launch may still be gaining momentum.
