Two weeks after Apple's first foldable went on sale, whether the ecosystem has kept up has become the deciding factor for upgrading. On November 9, it was revealed that in the Chinese market, social and AI apps such as QQ, Tencent Meeting, DeepSeek, and Wenxin, tools such as Bilibili, Qidian, and Meitu, as well as JD.com, Dewu, and Alipay, have all been adapted for iPhone Duo. On the gaming side, miHoYo announced on November 5 that Zenless Zone Zero will be adapted starting with version 3.3.1.
WeChat still leaves a black bar, and the system version determines the experience
iOS 27 only lets apps basically use the inner and outer screens; WeChat is a prime example—the vertical frame of the inner-screen dock is still black. Only starting with iOS 27.1 can developers fully utilize both screens, and iOS 27.2 adds Apple Pencil (USB-C) support. According to hands-on testing by Jiemian News, interfaces such as DeepSeek, Bilibili, and Meitu already fill the inner screen: AI chat apps can spread out their conversation lists and approach tablet-like efficiency, while video and community apps gain a smoother viewing experience through the hover/fold state.
Susan Prescott, Apple's vice president of Worldwide Developer Relations, said that the global App Store already has more than 100,000 apps built for iPhone Duo. The online China store has launched an "Apps optimized for iPhone Duo" feature, and app pages carry a "Designed for iPhone Duo" badge; offline, more than 2,000 developers attended over 50 workshops in 19 cities. But feedback on social platforms poured cold water on this: many people feel that simple improvements in presentation and interaction are not enough, and the true foldable experience that matches the price has not yet arrived. The motivation to upgrade is still in developers' hands.
