The Muse app, launched on September 8, has quickly gained traction, surpassing ChatGPT as the leading iOS free app in the U.S. with 730,000 downloads in just five days, according to analytics firm Sensor Tower.

The app's success has positioned it ahead of competitors like Claude and Grok, further solidifying its place in the rapidly evolving landscape of AI applications.9
