Apple launches iPhone Duo foldable with MLB app built for it
The baseball app splits the unfolded screen between a livestream and live box scores; MLB began work after Apple's September 9 announcement.
Apple launched the iPhone Duo, its foldable phone, on October 23, 2026. The device pairs a 5.4-inch cover screen with a 7.6-inch inner display that carries a Nano-texture finish.
MLB released a redesigned version of its app for the phone on the same day, built around the foldable form factor and issued ahead of the World Series, according to techradar.com. On the unfolded screen the app can run a livestream on one half while showing real-time box scores on the other.
MLB started development after Apple announced the iPhone Duo on September 9. The league also uses AI in its Game Day experience to generate extra information about plays, players and game situations.
MLB's history with Apple's devices goes back to the original iPhone, where it was among the first 500 apps, and it had an iPad app ready for that device's launch day. The league also worked with Apple on HTTP Live Streaming (HLS) to improve reliable live video delivery, including advertising insertion.
