MLB Updates Its App for Apple’s iPhone Duo Ahead of the World Series

MLB’s iPhone Duo update arrives with a useful test built in: the World Series. The league has adapted its app for Apple’s new folding phone just as fans prepare to follow Game 1 between the Milwaukee Brewers and Tampa Bay Rays, giving MLB a week of live baseball to see how people respond.

The iPhone Duo has a smaller outer screen and an inner display close to the size of an iPad mini when opened. That wider canvas could make watching a game and checking related information at the same time feel less cramped. MLB SVP of product for app and web Josh Frost said the league is especially interested in making its live broadcast experience more engaging.

“We plan to learn a lot in the next week of live baseball that we have here to see how this works, to see how our fans react,” said MLB EVP of media, business development and product Kenny Gersh.

Experience across Apple devices helped MLB move quickly

Apple announced the Duo on September 9, leaving developers little time to prepare before its launch. With limited access to the hardware, app teams largely relied on simulators running on other Apple devices to anticipate how their products would appear.

MLB could draw on years of work supporting both iPhones and iPads. Its At Bat app was among the first 500 apps released with the iOS App Store in July 2008, and the league has made a point of supporting Apple platforms around Opening Day. Gersh said that reputation for adopting new technology has helped baseball project an image beyond its traditional identity as “America’s pastime” and toward “America’s future.”

The challenge now spans more than a growing list of phone and tablet sizes. Fans expect digital experiences to work across devices ranging from small smartwatch displays to virtual reality environments, Frost said. The Duo adds another screen format to that mix, with room for developers to rethink how live coverage, scores and other app features share space.

Sports apps are adapting as Apple expands its role

MLB is among several sports organizations preparing for the device. Apps from MLS, the NBA and the PGA Tour have also been updated for the Duo’s foldable design.

Apple’s role in sports has grown alongside its hardware presence. The company holds exclusive streaming rights across baseball, motorsports and soccer, and has launched its own scores app. Its devices also appear on college football sidelines and on the wrists of professional surfers.

After seeing a preview of MLB’s updated app, Apple SVP of worldwide marketing Greg Joswiak said, “Sport has embraced us and we’ve tried to embrace sport.” He described the appeal as extending from how fans watch to how technology can help improve play on the field.

The larger screen could change the second-screen habit

Foldable phones may alter how fans keep up with a game. Their inner displays suit horizontal video better than a conventional vertical phone screen, while the extra room could support more simultaneous tasks. Teams may need to think beyond the familiar second-screen experience toward a third screen’s worth of activity.

Adoption, though, may take time. The iPhone Duo starts at $2,000 and is already backordered until 2027. Early reviews also found apps that hadn’t been adapted, sometimes producing awkward layouts. The Verge described the phone as “an early adopter special.”

For MLB, the World Series offers an early look at whether the new format changes how fans watch and interact with baseball. The league’s app is ready for the larger display; what matters next is whether fans find enough value in that extra space to make the Duo a regular part of game day.
