Meta AI assistant Muse has been online for 40 days and has downloaded 10 million times in the United States, and only 11 apps have reached that record.Meta AI 助手 Muse 上线 40 天美国下载量破千万，仅 11 款应用曾达成该纪录

IT House October 21st news, Meta's artificial intelligence assistant Muse has now joined the ranks of only more than a dozen mobile applications downloaded in the United States in 40 days. According to the latest data from Sensor Tower, a market intelligence agency, Muse has accumulated 10.9 million downloads since its launch in September, including 10.2 million in the US. Kara Lee, a senior insight analyst at Sensor Tower, said that only 11 other apps have reached this post-launch milestone to date, the last to do so being Meta's Threads in July 2023. Li mentioned that most of the other apps that reached this scale were mobile games, such as Fortnite, PUBG Mobile, Pokémon GO, and so on. In addition to Threads, Disney + is the only non-gaming app on this elite list. IT House noticed that Meta achieved this result, relying on the company's ability to promote new applications with its other products, and both Threads and Muse used this method. Threads is built on Instagram's social network, and its content has been integrated into Facebook and Instagram. The growth of Muse is not only due to Meta's promotion of this AI agent within a family of applications with 3.6 billion daily active users, but the company has also invested a lot of advertising resources to attract new Muse. Meta spent 39% of its entire advertising budget on promoting Muse in October, up from 23% last month, according to Sensor Tower. In addition, Muse climbed to 21st place on the US Brands list this month in terms of ad impressions, up from 73rd place in September. However, promoting an app and retaining users after the heat has faded are two different things. Muse's user retention is superior to AI competitors such as ChatGPT, Claude, and Grok. In the US market, the app has a 7-day retention rate of 30% and a 14-day retention rate of 23%. In comparison, the agency's data shows that the average 7-day retention rate of competing products is 19%, and the 14-day retention rate is 16%. Muse also reached another milestone that reflects user activity: on October 16, the number of daily active users reached 2.5 million for the first time, up 15% from last week. The latest Meta AI app to handle a wide range of tasks for users has been an explosive success since its launch. It reached the top of Apple's App Store at one time, and some indicators even surpassed the performance of ChatGPT when it was first launched. This new milestone once again opens the gap with the competition: ChatGPT had 3.7 million downloads in the United States in its first 40 days, while Grok and Claude had only 500,000 and 200,000 downloads, respectively, in the United States during the same period. Globally, ChatGPT has seen more downloads than Muse, with around 15 million downloads worldwide in the first 40 days of launch. But the two are not suitable for direct comparison, as ChatGPT targets a wider market. Muse is currently only available in the US and Canada, while the ChatGPT app has also attracted users in markets such as Japan, Brazil, and Germany (for example, Japan contributed 25% of its global installed base in the first 40 days of launch). Since its launch, Muse has almost always ranked first on the Apple App Store list in the United States, only briefly surpassed by the streaming app Kick on October 19. It had regained the top spot as of Tuesday local time. Muse has also been # 1 on the Google App Store for the past 30 days.
