#1 Free App in US Apple App Store on October 23 prediction

The Apple page that decides this question showed Muse from Meta ranked first among US free iPhone apps when it was read at 18:01 UTC on October 19. The listing reads "Your personal AI agent." That is a reading from four days before the October 23 check, not the answer itself. The lead looks fairly steady. An Apple chart page published October 18 had Muse first, followed by ChatGPT, Claude by Anthropic and Google Gemini. Two separate chart trackers, both dated October 18, also listed Muse at number one in the US. These are context, not the deciding record, but they point the same way. The case against is that the top spot has changed hands before. One news report dated October 15 said Muse had just been knocked off the top spot for the first time since launch, with Dave's Hot Chicken taking over. Muse was back in front by October 18. That shows a single rival can displace it, but it also shows Muse regained the spot. An older Apple chart capture, with no publication date in the record, had Sora by OpenAI first. I treat it as an earlier reading, not the current standing. Muse holds the lead and has recently recovered it, so I lean toward it still being first on Friday, October 23. The thing to watch is whether a surging newcomer, like the October 15 chicken-chain app, pushes it down the chart before the 12:00 PM ET check.
