## Summary

According to Sensor Tower data cited by TechCrunch, Meta’s AI companion Muse recorded 10.9 million downloads since its September debut, including 10.2 million in the United States. That puts the app in a group reached by only 11 other apps; Muse is currently available only in the U.S. and Canada. Meta also allocated 39% of its advertising spend to Muse in October, up from 23% the previous month, according to Sensor Tower.

In the U.S., Muse had 30% retention after seven days and 23% after 14 days, compared with averages of 19% and 16%, respectively, for ChatGPT, Claude and Grok. Its daily active users reached 2.5 million on October 16, a 15% week-over-week increase, also according to Sensor Tower.

## Why it matters (editorial interpretation)

Sensor Tower’s data suggests strong initial adoption for Muse in the U.S., while also indicating that Meta is directing a growing share of its advertising toward the app. Retention and usage metrics help contextualize the product’s performance against competitors, though they are limited to the markets where it is available.
