Those figures, supplied by Sensor Tower, place Muse behind some of Meta’s previous launches. Threads recorded more than 4.3 million U.S. downloads on its first day, and the Meta AI app drew 108,000 U.S. downloads at debut. Comparisons to ChatGPT are starker: that app topped half a million installs in the U.S. within a week, which, if divided evenly, equated to about 83.3K downloads per day, roughly twice the daily rate Muse has averaged to reach the same cumulative number.
Muse’s rollout is currently U.S.-only on iOS, and its Android presence lags: the app sits at No. 338 in Google Play’s Productivity category and Android download numbers are not yet available. Meta’s web and WhatsApp versions are also not included in the reported iOS estimates, so total early usage may be higher than the App Store figures suggest.
The launch comes as Meta positions agents as a central consumer AI bet, arguing these assistants will handle tasks on users’ behalf. That strategy faces both market and reputational headwinds. Muse arrived days after Meta agreed to a $18 billion multistate settlement, and the app requires users to share more personal information, a combination that could affect adoption among privacy-conscious consumers.
Competition for simple, everyday agents is already intense. Startups such as Instinct present a direct challenge, Instinct carries a $2.5 billion valuation, has $350 million in funding, and has recently pushed features like email addresses for users, inter-agent social interactions, integrations with Stripe and 1Password, and location-sharing. Those moves aim to make agents practical for real-world coordination and transactions, areas Meta will need to match to convert early interest into sustained use.
For now, Muse’s ascent on iOS offers Meta a credible entry into agentic consumer AI, but its longer-term success will depend on Android uptake, how broadly web and messaging usage grows, and whether Meta can reassure users about data and privacy as the company scales features and competition intensifies.
