Sensor Tower estimates 10.2M U.S. downloads for Meta Muse

Sensor Tower estimates reported by TechCrunch on October 20 put Meta Muse at 10.2 million U.S. downloads and 10.9 million worldwide during its first 40 days. Those totals count downloads, not the number of people who kept using the app. Separate U.S. retention and daily-active-user figures offer a short-term view of activity.

What the first 40 days say about downloads

Sensor Tower senior insights analyst Kara Lee said 11 other apps had reached 10 million U.S. downloads within their first 40 days. The figures place Muse among a small group by that measure, while leaving the question of ongoing use to other metrics.

The first-40-day U.S. counts TechCrunch attributed to Sensor Tower were:

Each figure covers the same market and launch window. They compare download totals, not how often people returned to each app.

Retention and daily activity add a short-term view

Sensor Tower put Muse’s U.S. retention at 30% after seven days and 23% after 14 days. The reported averages for ChatGPT, Claude and Grok were 19% and 16%, respectively. These rates cover the first two weeks, rather than longer-term adoption.

Sensor Tower also recorded 2.5 million U.S. daily active users on October 16, a 15% increase from the previous week. That is a count for a specific day; the 10.2 million download figure covers the first 40 days. The two measures describe different aspects of activity.

Why Muse’s worldwide total is hard to compare

TechCrunch reported 10.9 million worldwide downloads for Muse in its first 40 days, compared with about 15 million for ChatGPT over its first 40 days. The comparison has different market footprints: at the time, Muse was available in the United States and Canada, while ChatGPT had broader international reach. Japan accounted for 25% of ChatGPT’s global installs during that period, according to the same report.
