- Prospective iPhone Duo owners checking app support
- Worth noticing
- It distinguishes folded compatibility from unfolded layouts, and labels many entries “Unconfirmed” rather than treating a recent build as proof.
Field notes
The homepage describes coverage as the 100 most-downloaded apps plus top-grossing titles, alongside a broader tracker count of 398. Visible rows pair app categories and rankings with folded and unfolded results, and often a rebuild date; examples include Capital One Mobile, ChatGPT, and BigFuture School. The page also shows US/China controls and a Chinese-language option. Its extracted text does not expose the underlying “How we know” method.
