Meta's Muse AI Agent Cracks the App Store's Top Three on Thin Downloads

Meta's AI agent Muse reached No. 2 on Apple's US free-apps chart by September 10, 2026, on more than 83,000 iOS downloads, according to Sensor Tower data cited by TechCrunch, and Meta shipped a Mac app for Muse on September 17. Meta shares rose roughly 0.6% to $657.65 as JPMorgan upgraded the stock from Neutral to Overweight and lifted its price target from $640 to $820. The ranking belies thin demand: Threads drew 4.3 million US downloads on its first day and Meta AI opened with about 108,000, while Muse sits at No. 338 in Google Play's Productivity category and charges $20 a month for the Power tier (500 million tokens) or $100 a month for Maximum (3 billion tokens) after a free tier capped at 100 million tokens a week.

Meta's AI agent Muse climbed to No. 2 on the US App Store within two days of launch and just picked up a Mac app, but its download numbers are a fraction of what Meta's own apps have pulled off before. Meta's new AI agent Muse launched on September 8, 2026, on iPhone, Android, the web, and inside WhatsApp. It took about 48 hours to turn into a genuine App Store moment. According to data from Sensor Tower cited by TechCrunch, Muse moved from No. 4 to No. 2 on Apple's US free-apps chart by September 10, on more than 83,000 iOS downloads. Meta shares rose roughly 0.6% that morning, to $657.65. JPMorgan upgraded the stock from Neutral to Overweight, lifting its price target from $640 to $820. Wall Street noticed. Then, nine days later, on September 17, Meta shipped a Mac app for Muse, expanding it past its iPhone-only debut. The desktop version, according to 9to5Mac, reaches into a user's files, calendar, notes, and messages - and it keeps working in the background even after you close the window. You choose what it can touch. It doesn't need you sitting there watching it work. That's the actual pitch: an agent that runs your errands, not a chatbot waiting for your next message. Muse can book a flight, sort your calendar, and clear the kind of to-do list that spreads across a dozen apps. Meta built it to run on what it calls Muse Secure VM. Each user gets an isolated Linux box in the cloud, holding the agent, a browser, and that person's connected accounts. Meta's AI research team says the agent never sees your passwords or payment details directly, and a separate watcher process called Sentinel has to approve anything before it reaches the open internet. Thin Numbers Behind a Big Rank Here's the thing: a No. 2 spot on the App Store sounds like a hit, but the numbers under it are thin. Threads pulled in 4.3 million US downloads on its first day. Meta AI, Meta's standalone chatbot app, opened with about 108,000. Muse needed two full days to clear 83,000. On Android, it's worse. Muse sits at No. 338 in Google Play's Productivity category, nowhere near the charts that count. Meta Reportedly Plans Camera-Free Luna Glasses After Privacy Backlash https://startupfortune.com/meta-reportedly-plans-camera-free-luna-glasses-after-privacy-backlash/ Meta is reportedly building camera-free smart glasses code-named Luna, expected to debut at Meta Connect on September 23 and could ship as soon as October. The device swaps the lens for six microphones and voice-based AI, arriving after a year of lawsuits and investigations into covert filming with Ray-Ban Meta glasses. - meta smart glasses without camera luna https://startupfortune.com/meta-reportedly-plans-camera-free-luna-glasses-after-privacy-backlash/ - when will meta luna glasses be released https://startupfortune.com/meta-reportedly-plans-camera-free-luna-glasses-after-privacy-backlash/ Chart position and demand aren't the same thing, and Meta knows it. A high rank on a free-apps chart, especially in a slow week for new launches, tells you people are curious enough to tap install once. It doesn't tell you whether they open the app again on day three, and it says nothing about whether anyone actually pays. Muse is free up to 100 million tokens a week, then $20 a month for the Power tier and 500 million tokens, or $100 a month for Maximum and 3 billion tokens. Meta requires a payment card just to activate the free tier. No card, no access. That alone filters out anyone not serious about trying it. Pricing built around token limits, rather than locked features, only makes sense if Meta expects real usage to climb past that free ceiling fast. That's the bet: people will hand an agent enough tasks to blow through 100 million tokens a week. So far, it hasn't shown up. Nothing in the download numbers says that behavior exists yet. The Real Race The bigger question is what Muse is actually racing against. OpenAI's ChatGPT agent already gives sessions their own sandboxed computer, with a secure browser takeover mode. Anthropic's Claude ships computer-use tools that ask permission before touching a new app. xAI's GrokBot entered beta on August 11, 2026, with its own persistent cloud agent. Same idea, four times over. Meta, OpenAI, Anthropic, and xAI have all landed on it within weeks of each other: give the model a machine of its own, not just a chat window. Meta's bet is different in one respect. It's betting that per-user VM isolation, not model quality alone, is what convinces people to trust an agent with their calendar and their credit card. Meta hasn't said how many of those 83,000-plus downloads turned into a second session, let alone a paying subscription. Frankly, that number matters more than any App Store rank. And it's the one Meta hasn't published.
