MLB App Redesigned for iPhone Duo Ahead of World Series
Major League Baseball pushed a major update to its official app tailored specifically for Apple's newly launched iPhone Duo. Timed for the start of the World Series, the software allows fans to stream live action on the top display while tracking box scores below.
How the iPhone Duo transforms live baseball
The redesigned app leverages the foldable form factor so viewers never have to sacrifice stats for video.
Hours after Apple launched its first foldable, Major League Baseball delivered an update engineered around the hardware. Instead of treating the device like a blown-up smartphone screen, the MLB app specifically accommodates the crease and folding angles.
When propped up like a miniature laptop on a desk, the app automatically places the live game stream on the upper half of the 7.6-inch inner screen. The lower half hosts dynamic, real-time box scores and Gameday tracking, removing the annoyance of toggling between video and statistics during crucial innings.
Users can also view feeds on the compact 5.4-inch cover screen or split the expansive inner display side-by-side with messaging apps and social media feeds.

| Official launch date | October 23, 2026 |
A 44-day sprint to the World Series
Engineering teams had minimal time to prepare. MLB built and deployed the custom interface in only 44 days following Apple's initial September 9 preview of the foldable hardware.
The release targets Game 1 between the Tampa Bay Rays and the Milwaukee Brewers. According to MLB Chief Technology Officer Sean Curtis in an interview with TechRadar, the goal was to unite the league's high-resolution video streams with deep statistical tracking natively on the new canvas, rather than forcing fans to compromise on a flat view.
Baseball has always been a stat-heavy sport, making traditional phone streaming feel compromised whenever you wanted to check pitching matchups. If more developers embrace the tabletop split layout as quickly as MLB did, the high price tag of foldables might finally feel justified by software utility rather than novelty.
Availability and pricing
The updated MLB app is available worldwide via the App Store as a free update for subscribers. Getting the hardware to run it is another matter: as Apple's $1,999 iPhone Duo sells out in minutes, new retail inventory across the US, UK, and Europe remains severely constrained, with some carrier orders stretching into next year.
Frequently asked questions
Does the MLB app require an unfolded iPhone Duo to work?
No, the app runs normally on the 5.4-inch external cover screen, but opening the 7.6-inch interior display enables the split tabletop video and stats view.
Can you run other apps alongside MLB on iPhone Duo?
Yes, the update supports running the MLB stream side-by-side with social feeds, group chats, or sports discussion apps on the expansive inner display.
