100,000 iPhone Duo apps is a start, but there’s a long way to go

AI-summarised brief · reviewed before publication

Apple announced that more than 100,000 apps have been built or refactored for the iPhone Duo, its first foldable model. The figure includes apps that fully support the dual-display layout, but many others remain in a middle ground or are outdated. Developers used Xcode 27.1 and the iOS 27.1 SDK to create Duo‑ready apps, while older SDKs produce suboptimal or legacy experiences. The rollout shows a mix of best‑case, usable, and poor‑adapted apps across the App Store.

💡 Why It Matters

  • · The split in app readiness signals how quickly the ecosystem can adapt to new hardware, affecting user experience and developer priorities.
  • · It highlights the importance of timely SDK updates for maintaining relevance in a rapidly evolving device landscape.
