Apple says the App Store now has well over 100,000 apps built for iPhone Duo, with thousands more being added daily. Reports describe both expanding developer support and apps that have yet to adapt to the device’s screens.
- Apple said well over 100,000 apps built for iPhone Duo are live in the App Store and thousands of optimized apps are added each day.
- Apple said more than 2,000 developers attended over 50 in-person workshops in 19 cities worldwide.
- Optimized apps can use the device’s inner and outer displays; older apps may run with empty space around them on the inner screen.
- Examples of optimized apps include Microsoft Word, Etsy, Zoom and Halide Mark III. MacRumors also lists apps that remain unoptimized, including Google Docs, DoorDash and Venmo.
- Apple says standard SwiftUI and UIKit components can adapt automatically, while developers can use additional APIs to tailor apps to different layouts and device positions.
