Apple Says iPhone Duo App Catalog Tops 100,000 as Supply Delays Stretch Into 2027
Apple says iPhone Duo now has 100,000 optimized apps, but delayed rollouts and supply shortages still shadow the $1,999 foldable's strong market debut.
Summary
On Friday, November 6, 2026, Apple said the App Store had surpassed 100,000 apps built for iPhone Duo, with thousands added daily, addressing launch criticism that its foldable lacked optimized software. Unoptimized apps waste screen space with a side black bar and can bury controls in overflow menus. More than 2,000 developers attended over 50 Apple workshops across 19 cities to test Duo and get support. Susan Prescott, Apple’s vice president of Worldwide Developer Relations, said optimization updates are accelerating.
Starting at $1,999 for 256GB, Duo sold out within hours; shipments have slipped into 2027, and Apple said this week it is hard to predict when constraints will ease. More than a dozen newly highlighted apps include Microsoft Word, Outlook, Zoom, NBA, NHL, Etsy, LTK, Goodnotes, Extra and Halide Mark III, joining Netflix, YouTube, Instagram and WhatsApp. Apple’s wider iOS 27 optimization roster names Spotify, CBS, Tubi, BBC iPlayer in the U.K., Yahoo Fantasy Sports, Sportsnet in Canada, Facebook Messenger, Google Chat, ChatGPT, Grok Bot, Microsoft Copilot, Excel, PowerPoint, SAP Concur, monday.com, PDF Expert, Documents, iA Writer, Substack, The Washington Post, Yahoo News, FOX News, Kalshi, Yahoo Finance, Canva, Suno, Tinder, Google Translate, Strava, Alma, Withings, MyFitnessPal, Bevel, Transit, Citi Bike, ParkMobile, Viator, Tesla Robotaxi, Priceline, Kroger, Domino’s, Taco Bell, Untappd, The Weather Channel, FOX Weather and RainViewer. Rollouts remain incomplete: Spotify still displayed the black bar, with no update available on the tested Duo.
