Does Strava work on iPhone Duo?
Not announced yet. Strava hasn't said when Strava will get an iPhone Duo layout. It still opens on the Duo, but won't fill the inner display until it's updated.
- Not announcedNo announcement from Strava that we have found, and the current App Store release notes don't mention iPhone Duo.
Until it's updated
What an app does on iPhone Duo before its developer adapts it. Which of the open cases applies to Strava depends on the tools its current version was built with, and we haven't seen it on the device.
Closed
On the outer display it looks and works as it does on any iPhone.
Open, built with older tools
An app last built with Xcode 26 sits in an iPhone-shaped window on the inner display, with black borders around it.
Open, built for iOS 27
An app built with the iOS 27 SDK resizes to use more of the inner display, with some space left over.
Open, built for iOS 27.1
Only an app built with the iOS 27.1 SDK reaches the edges of the inner display and moves its bar buttons to the side. Apple calls that “optimized for iPhone Duo”.
About Strava
Strava has no announced version for iPhone Duo. As of October 6, 2026, the current App Store release is version 483.0.0, from September 30, and its release notes don’t mention the Duo. Strava has made no announcement that we have found.
Strava is used with the phone closed during a workout and open afterwards, and that second part is where the Duo could help: a map beside the splits. Strava hasn’t announced anything. Running apps with a Duo layout include RunRev and Runmo.
Strava will still open on iPhone Duo, like every app on the App Store. Closed, it looks as it does on any iPhone. Open, it won’t reach the edges of the inner display until Strava rebuilds it with Apple’s iOS 27.1 tools, which Apple only cleared for App Store submissions on October 5. More in how apps that aren’t updated run on iPhone Duo.
