Muse, Meta’s latest app based on agentic artificial intelligence, reached second place on the lists of the most popular apps in the U.S. App Store after recording more than 83,000 downloads on iOS devices, according to data provided by Sensor Tower. The app is currently available only in the United States.
The figure represents an important starting point for assessing consumer interest in the app, but it also reveals a slower launch than some of Meta’s previous releases. Threads surpassed 4.3 million downloads in the United States on its launch day, while the Meta AI app recorded about 108,000 downloads on its first day. This comparison shows that Muse has not yet approached the level of momentum surrounding Meta’s other products.
Mixed Performance Across iOS and Android
Muse’s ranking on Apple’s App Store improved from fourth place on Wednesday to second place in the latest measurement, indicating that it continues to rise within the store rather than seeing interest stop on launch day. Its position on Android is different, however: it ranks 338th in the productivity category on Google Play, while download figures for that platform are not yet available.
Sensor Tower’s estimates also do not cover every usage channel. The app is additionally available on the web and through WhatsApp, and these channels are not included in the iOS download figures used for comparison. Therefore, the number of downloads cannot be considered a complete indicator of Muse’s user base or its actual level of use.
Comparison With Agentic AI Apps
Muse’s performance also fell below ChatGPT’s launch in the United States. ChatGPT surpassed half a million installations within less than a week of reaching the U.S. market, which was the only market where it was available at the time. The article estimates that an even distribution of this figure would have meant about 83,300 downloads per day, a level that Muse took roughly twice as long to reach.
Meta is betting that AI applications will move from providing users with answers to carrying out tasks on their behalf. The company is not moving in this direction alone; the article points to competition from Google Gemini Spark and Anthropic Claude Cowork, in addition to the Instinct app, which operates through text messages, attracted $350 million in funding, and reached a valuation of $2.5 billion.
Why Do These Numbers Matter?
The editorial reading from certi.news is that second place alone is not enough to prove Muse’s success, but it offers an early indication that Meta’s entry into the consumer-agent market does not automatically guarantee a repeat of the success of Threads or Meta AI. The comparison remains limited because of differences in platforms, distribution channels, and measurement periods, as well as the absence of Android, web, and WhatsApp figures.
Trust may also affect adoption of the app, as Muse requires users to provide Meta with more personal information. Its launch came days after the company agreed to an $18 billion multistate settlement in a lawsuit related to the consumer harms of social media, amid a record of privacy cases, fines, and legal actions in the United States. These facts do not prove that privacy concerns are the reason for the slower downloads, but they explain one of the open questions surrounding Meta’s ability to persuade users to give its agents more data and permissions.
