Cisco’s Webex is now fully optimized for the brand-new iPhone Duo, bringing support that adapts automatically to both displays and multiple device orientations. Rather than treating this foldable like an oversized phone, Webex takes advantage of the Duo’s dual-screen design, letting users view more meeting participants, keep shared content visible across screens, or collaborate on a whiteboard while partially folded. For anyone who wants to multitask, Webex also works alongside other apps using Split View on the Duo’s large inner display.
What Real Support Looks Like
Webex was built natively for the Duo from day one. That means the app dynamically adjusts its layout whether the device is fully open, closed, or used in between those states. Key elements like toolbars and navigation shift to maximize vertical space in every orientation. Shared content—such as presentations or documents—stays in view, while participant video tiles expand to fill unused screen real estate.
Whiteboarding is another area getting special attention. When collaborating on sketches or diagrams during a meeting, Webex keeps the canvas interactive and visible, even when sharing space with other apps through Split View. When part of the UI overlaps the hinge, controls recede or shift to avoid interference with the fold.
Multitasking That Feels Native
The adaptive design isn’t limited to meetings. With Webex on iPhone Duo, Switch between conversation, shared content, and meeting tiles smoothly. If you want to use Webex alongside another app, the Duo’s multitasking lets you split the screen. Webex works flexibly in each half, keeping core meeting controls and shared content accessible even when multitasking.
Like other developers embracing the Duo, Webex completed its optimization in alignment with Apple’s new SDKs and interface guidelines. These let apps handle size changes, reposition navigation, and adjust content fluidly across both displays.
Broader Impacts & Ecosystem Growth
The Webex update is part of a wider surge of iPhone Duo–tailored software. Apple has said there are now “well over 100,000 apps built for iPhone Duo” live in the App Store, with thousands more — optimized for the foldable format — arriving every day. Apps rebuilt using the iOS 27.1 SDK or newer can use full-width layouts, reposition controls, and stretch across both screens. Those built with older SDKs still work, but often appear centered with black margins or limited layout capabilities on the inner display.
To help users identify these updated apps, Apple has introduced a “Made for iPhone Duo” badge on App Store product pages. Also, the store now includes curated collections like “Popular Apps on iPhone Duo” and “Great Games on iPhone Duo.” Beginning April 2027, all new submissions to the App Store will need to include Duo-specific screenshots — and non-optimized ones will be required to show black bars as proof of compatibility status.
Professionals behind the scenes say Apple’s developer support has been hands-on: over 2,000 engineers and app creators have participated in more than 50 in-person workshops in 19 cities globally. These sessions gave devs physical Duo hardware to work with ahead of public availability, helping refine layouts, multitasking behavior, and performance across both displays.
Why This Update Matters
Webex supporting iPhone Duo natively means foldable users now have a fully functional, polished collaboration tool optimized for their device. No more awkward phone-sized windows or clipped interfaces during group calls. Meetings, screen sharing, whiteboarding, and multitasking all feel like they were meant for this dual-display format.
This moment signals we’re past the launch phase and into a world where the Duo’s dual screens aren’t novelty — they’re a practical asset. Watching which essential apps don’t have Duo support yet — or how well optimized they are — will be crucial over the coming months. A gap in optimization, especially among high-use apps, could become the Duo’s Achilles’ heel.
Looking ahead: expect more foldable-first innovations like video layout options, gesture-based multitasking, or adaptive interactions around the hinge. Webex’s full adaptation raises the bar for every app in the ecosystem — and for iPhone Duo users, the days of “this doesn’t look right when unfolded” may finally be over.
