Meta’s Muse Tops U.S. Free-iOS Chart After 730,000 Downloads

Meta’s new Muse agent was built to take action across a person’s digital life. Its first market test is delivering a more immediate result: Muse overtook ChatGPT as the leading free iOS app in the United States and logged about 730,000 downloads in roughly five days, according to Sensor Tower.

The ranking puts Muse ahead of ChatGPT, Claude, Grok and Meta’s own Meta AI app in the U.S. free-iOS chart. Muse passed ChatGPT for the top spot on Friday, CNBC reported, less than two weeks after Meta introduced the service on September 8.

A sharp early signal, with a comparison caveat

Sensor Tower said Muse’s cumulative downloads exceeded those of ChatGPT, Claude and Grok in comparable post-launch windows. But it also cautioned that those products had staggered releases across Apple’s App Store and Google Play, a difference that affects direct download comparisons.

The product behind the chart position

Muse is Meta’s attempt to turn an AI assistant into a service that does work rather than only produces answers. Meta says the agent is powered by its Muse Spark model and is rolling out in the United States on iOS, Android and muse.ai.

What Meta says Muse can handle

• It can send email, book travel, open a browser and fill out forms after a user gives it a task.
• For longer jobs, it can continue after the app is closed and return when something changes or when it needs approval.
• Meta says it asks for approval before sensitive actions, including sending email or making a purchase.

Those capabilities make the app’s early reach more notable than a simple chatbot launch: Muse asks users to trust it with work across connected services. Meta says people choose which apps to connect and how much access to grant, while credentials are stored so the agent can use them without seeing passwords or payment methods.

Free access is only the first layer

Meta offers Muse free for most use, while CNBC reported monthly subscription tiers of $20 and $100, depending on usage. The pricing creates a route to revenue beyond advertising if the product can persuade people to use an agent often enough to pay for heavier access.

For now, the figures show a powerful launch burst, not a settled consumer habit. CNBC noted that it remains unclear how long Muse will stay a hit; other AI services have also surged after release without remaining blockbusters. The next meaningful test is whether a chart-leading download count turns into repeat use of an agent that can act on users’ behalf.
