Muse from Meta is still sitting at the top of the free-app charts in two of its four markets, more than two months after launch. As of the morning of 15 November 2026, the app is #1 Free on the App Store in Canada and Japan, #1 Free on Android in Canada and the United States, and #2 Free on the App Store in the US. It is the first AI agent — not a chatbot, an agent that does things on your behalf — to hold the top of the App Store, and it has not given that position up easily.
Where Muse ranks today
The table below is Ascension’s daily chart read for 15 November 2026, taken at 5:57 AM ET. Each figure is the app’s best position on that country’s main Top Free chart that day.
| Country | App Store (iOS) Free | Google Play (Android) Free |
|---|---|---|
| United States | #2 | #1 |
| Canada | #1 | #1 |
| Japan | #1 | #2 |
Two details sit underneath the headline numbers. First, Muse is #1 of the four AI agents Ascension tracks, and #14 of 888 AI apps across both stores. Second, the app is still gathering ratings fast: 916,000 combined ratings across the App Store and Google Play, 4.8 stars on both, with more than 151,000 new ratings in the past seven days alone. Ratings are not downloads, but a rising rating count is the earliest public sign that new people keep installing an app.
How Muse got here: 32 days at #1 in the US
Muse launched in the United States on 8 September 2026, then in Canada, and arrived in Japan on 23 October 2026 — the first country outside North America to get it. Its chart history, tracked day by day by GameQuant and published on 5 November, reads like a launch most apps never get:
“Muse from Meta first appeared in the US App Store’s Top Free Apps chart on 9 September 2026, at #4. Nine days later it was #1, and it stayed there every day from 18 September to 19 October: 32 days in a row at the top of the free apps chart in the world’s biggest app market.”
GameQuant, 5 November 2026
Since the streak ended on 19 October, Muse has traded places at the top rather than owning it — back at #1 on 25 October, #2 on 1 November. Outside the US it has been steadier: on 1 November it was #1 in Japan, Singapore and Canada. A snapshot of Japan’s Top Free chart on 15 November still shows Muse at #1, with ChatGPT at #2.
Meta’s own numbers, given to investors on the third-quarter earnings call on 21 October, frame the same story in people rather than positions: more than 10 million people in the United States and Canada had set up Muse in about six weeks, with roughly a quarter using it on any given day. Chief executive Mark Zuckerberg told the call the app had been “#1 in the App Store almost every day” since launch.
What the downloads actually say
Chart positions are not downloads, so the download estimates matter — and they need their labels kept on. The best-documented weekly comparison comes from FoxData estimates, amplified by Meta AI chief Alexandr Wang on 4 November: in the week to 29 October 2026, Muse had an estimated 942,000 downloads on Apple’s US App Store, against 556,000 for ChatGPT — a ratio of about 1.7 to 1. The same comparison puts Gemini at 341,000 and Grok at 239,000 for that week.
But the same source shows the other half of the picture. On Google Play in the United States that week, ChatGPT still led, with 509,758 downloads. The 1.7-to-1 headline covers Apple’s US store only, not all app downloads. Sensor Tower’s estimates, reported separately, put Muse at about 10.2 million US downloads in its first 40 days, and 10.9 million downloads by 21 October. Google Play lists the app at 10 million-plus installs.
| Figure | Value | Status |
|---|---|---|
| US App Store downloads, week to 29 Oct 2026 | 942,000 (Muse) vs 556,000 (ChatGPT) | Third-party estimate (FoxData) |
| US Google Play downloads, same week | ChatGPT ahead at 509,758 | Third-party estimate (FoxData via ASO World) |
| US downloads, first 40 days | ~10.2 million | Third-party estimate (Sensor Tower) |
| People who set up Muse, US + Canada, ~6 weeks | 10 million-plus | Meta’s own figure (Q3 earnings call, 21 Oct) |
| Daily use among those people | ~25% | Meta’s own figure (Q3 earnings call, 21 Oct) |
| Combined ratings, 15 Nov 2026 | 916,000, 4.8 stars | Store data (Ascension) |
What a chart position proves — and what it does not
This is where the chart story is usually told badly. A #1 rank proves that a lot of people are installing an app right now. It does not prove revenue, retention, or that those people keep using it. Three checks keep the story honest:
1. The grossing charts tell a different story. Muse is a free app with no in-app purchases on the App Store, according to Ascension’s listing. On the grossing charts it barely registers — #83 on Canada’s Android Top Grossing chart, and inside the Productivity grossing category only (#15 on iOS in Japan, #8 on Android). A free agent that does things for you earns its money elsewhere, if it earns it at all yet.
2. Shopping is the use case, not chatting. Zuckerberg told investors that shopping is Muse’s most common use, with more than a quarter of people using Muse engaging in it, at an average purchase size over $200. Meta has published no revenue figure, no count of buyers and no total spend — so the shopping story is real but unmeasured in public.
3. The moat is the agent, not the model. Muse’s pitch is doing things: calling businesses, shopping, booking. That is why the chart matters beyond bragging rights — it is the first time an agent, rather than a chatbot, has topped the App Store, and it has stayed at or near the top for two months. The question now is whether the position survives the novelty phase, when the next market opens and the first bill for all that free compute comes due.
What to watch next
Three things will decide whether this chart run becomes a durable lead or a launch spike. First, whether Muse holds #1 in Canada and Japan through the rest of the quarter — the daily readings have not moved since 14 November, which is steadiness, not growth. Second, which country is next: Meta has given no date for Europe, and has said each country needs adaptation and connector work because the agent is compute-intensive to run. Third, whether the grossing rank ever climbs — if shopping really is the top use, the money should eventually show up in the charts that count it.
For now, the plain reading stands: two months after launch, Meta’s agent is still the most-installed free app in Canada and Japan, and a close second in the United States. The chart says people are still trying Muse. It does not yet say they are paying for it — or staying.
