Meta’s AI companion app Muse reaches 10 million downloads in the United States within 40 days, according to app analytics cited by multiple outlets. Quartz, 9to5Mac, and TechCrunch all report that the milestone places Muse among a small group of apps to achieve the benchmark in that timeframe.
Beyond download speed, the coverage focuses on user retention. Quartz and TechCrunch say Muse keeps a larger share of users after seven and 14 days than competing AI apps, citing data that compares Muse’s early retention with that of ChatGPT, Claude, and Grok (as described in the Quartz summary). 9to5Mac also highlights Sensor Tower’s reporting that Muse outpaces peers in keeping users, without adding different retention time windows in the provided summary.
Overall, the sources largely agree on the key figures—10 million U.S. downloads in 40 days—and the general context that Muse’s early retention is stronger than rivals’ rates as measured by the same analytics report.
