Top trending apps on App Store Free: September 13
ChatGPT: OpenAI's consumer chat app. It has held rank 1 on this board for consecutive snapshots, including September 12. The ChatGPT topic page tracks the same product as a search keyword.
Paramount+: CBS Interactive streaming app. New at 2. Paramount+ is the home of Avatar: Seven Havens (premiere October 9) and is running a trailer that still ranks 2 on YouTube. Ember Picks history shows a prior all-apps free peak on 2026-07-13.
Muse from Meta: Meta's creative app. Climbs 7 to 3 after sitting behind TikTok Pro yesterday. No separate product-launch note was found for September 13 beyond the rank move.
Vinted: Pre-loved marketplace: Resale marketplace. Falls 2 to 4 but stays in the top 5.
Kalshi: Trade Football & more: U.S. regulated prediction-market app. New at 5. Kalshi lists contracts on football and on App Store ranks themselves, which matches a college-football Saturday (Ohio State-Texas) and this chart.
Netflix Game Controller: Netflix's game-controller companion. New at 6, replacing the main Netflix app that was 9 yesterday.
Polymarket: Trade Live Sports: Crypto-settled prediction market. Falls 6 to 7 but remains the second sports-trading app in the top 10 with Kalshi at 5.
TikTok Pro - Events: TikTok's events-oriented client. Falls 3 to 8.
Google Maps: Navigation. Falls 5 to 9.
ReelShort - Stream Drama & TV: Vertical drama streamer. New at 10. No widely reported U.S. news trigger identified for September 13, 2026 beyond the chart entry.

What today's App Store Free apps reveal
The free chart split into three jobs: chat (ChatGPT 1, Muse 3), video (Paramount+ 2, Netflix Game Controller 6, ReelShort 10, TikTok Pro 8), and betting on sports outcomes (Kalshi 5, Polymarket 7). Maps and Vinted are the leftover utilities. Gemini leaving the top 10 is the clearest AI-app fade versus ChatGPT's lock on rank 1. Paramount+ at 2 is the weekend's content install, not a new ChatGPT challenger.
