# DuoKits — iPhone Duo app directory

> Independent, hand-checked directory of apps for iPhone Duo, Apple's foldable iPhone (iOS 27.1, 7.6-inch inner display, 5.4-inch outer display). 107 apps. Last updated October 24, 2026. Structured data: https://duokits.com/apps.json. Available in English, Simplified Chinese (/zh), Japanese (/ja) and Korean (/ko).

## Tiers

- **Built for Duo**: Does something specific with the hardware: a different layout folded and unfolded, Split View, the half-open position or the outer display.
- **Adapted**: Rebuilt with the iOS 27 SDK or later, so it resizes to the 7.6-inch inner display instead of showing black borders. With the iOS 27.1 SDK it can use the whole screen.
- **Compatible**: Runs unchanged. It looks normal on the outer display and keeps its phone layout, with black borders, when unfolded.
