Data released by Meta on October 20 shows that its artificial intelligence app Muse has reached 10.20 million U.S. downloads within 40 days of its release in September (month 9) (10.90 million total downloads), making it one of only 12 mobile apps in history to achieve this milestone.
Sensor Tower's analysis shows that previously only a few non-gaming apps such as Threads (July 2023, month 7) and some mobile games had entered this rank. As an AI agent app capable of handling tasks on behalf of users, Muse's rapid growth was driven by traffic from Meta's vast app ecosystem and a significantly expanded advertising investment, with its share of advertising spending in October (month 10) rising from 23% the previous month to 39%.
In terms of user stickiness, Muse's 7-day and 14-day retention rates in the U.S. reached 30% and 23% respectively, outperforming the industry competitors' average, and its daily active users first touched 2.50 million on October 16.
A same-period comparison shows that its 40-day downloads surpassed the U.S. market performance of ChatGPT (3.70 million), Grok (500,000) and Claude (200,000) over the same period. This breakthrough indicates that leading tech companies are leveraging ecosystem advantages and capital matrices to accelerate the scaling and popularization of consumer-grade AI applications.
