MLB App Leverages iPhone Duo's Foldable Screen

Major League Baseball has unveiled a redesigned app experience to coincide with the launch of Apple's new iPhone Duo on October 23, 2026. This updated app takes full advantage of the device's unique foldable form factor, offering a large 7.6-inch inner display for viewing content like the World Series, which is set to begin the same day. The MLB app development team worked rapidly, preparing the new experience in just 44 days following the iPhone Duo's announcement on September 9, 2026.

The redesigned app allows for versatile viewing modes, including a laptop-like orientation or a split-screen setup. This enables fans to watch live streams on one part of the display while simultaneously viewing live statistics on another. MLB aims to provide a more integrated and natural way for fans to follow the game. Sean Curtis, MLB's chief technology officer, expressed excitement about merging the Game Day experience with live video and real-time stats. He also highlighted the use of artificial intelligence to generate additional context for plays, players, and game situations, offering deeper insights.

This collaboration signifies a continued evolution of the long-standing relationship between MLB and Apple, dating back to the early days of the App Store. The league was among the first apps available on the original iPhone and had an iPad app ready for its launch day. This latest innovation with the iPhone Duo explores how novel hardware can transform the fan experience, with further refinements planned during the off-season based on fan reception during the World Series and upcoming games.
