Recent App Store data shows Muse from Meta holding the #1 free spot since its early September launch, with Vinted stable at #2 and ChatGPT at #3 as of October 6. Muse's edge stems from its agentic design, enabling multi-step tasks like email management and form completion through connected services, which fueled rapid downloads exceeding 2.5 million in weeks and displaced ChatGPT. Vinted benefits from steady marketplace engagement, while ChatGPT retains strong retention despite the shift. With rankings tightly contested and no major releases imminent before October 9, trader sentiment reflects uncertainty over short-term momentum swings among AI agents and established apps like Gemini or Threads.
