ChatGPT: OpenAI consumer chat app, rank 1 for a second day. No new model-launch headline is required to explain a hold at the top of the free chart.

Drop-offs: Canvas by Instructure (was 7), Depop (was 8), Capital One Mobile (was 9).
ChatGPT, NBA 2K HQ, Vinted, and TikTok Pro - Events held ranks 1 through 4.
What today's App Store free board reveals
Utility and school apps are eating the fashion slots. ParentSquare at 6 and Teams at 10 are calendar products. Depop leaving while Vinted holds 3 keeps one resale app, not two.
NBA 2K HQ at 2 is still a launch-week companion, not a perennial like WhatsApp. 2K timed the app for August 21 at 8:00 a.m. PT, five days before Early Access on August 26 and 14 days before the September 4 console launch. ChatGPT at 1 is the fixture. The chart did not freeze: three names rotated at 8, 9, and 10, which is a 30 percent turnover in the published 10.
