07. FAQ

Questions, answered.

Everything you need to know about native app development for the iPhone Duo.

What exactly is a native iPhone Duo app?
An iPhone Duo native app is built from the ground up using Swift and SwiftUI, specifically tailored for the device's dual screen and foldable architecture. Unlike traditional iOS apps that get stretched across two screens, we design custom dual pane user experiences, seamless multitasking workflows, and spatial interfaces that utilize the full hardware capabilities.
Why shouldn't I just port my existing iOS app to the Duo?
Porting or stretching an existing app often results in wasted screen real estate, awkward UI scaling, and a disjointed user experience. A custom dual screen iOS app takes advantage of the unique form factor, allowing for true side by side multitasking, companion views, and immersive media consumption that feels native to the foldable Apple ecosystem.
Will the app still work on standard, single screen iPhones?
Absolutely. Through responsive iOS design and adaptive layout techniques in SwiftUI, your app will gracefully collapse into a standard single screen experience on traditional iPhones, while expanding to reveal the full dual pane interface when opened on an iPhone Duo.
Do you handle both UI/UX design and SwiftUI development?
Yes. Through our exclusive partnership with AA Immersive, we offer full stack iOS app development. Our team handles everything from initial foldable iOS app design and prototyping to final SwiftUI engineering and rigorous QA testing.
How much does custom iPhone Duo app development cost?
The cost of dual screen app development depends on the complexity of your features, the scope of the UI/UX design, and whether you need backend integration. We provide custom quotes based on your specific business goals. Contact us to request a consultation and a detailed project estimate.
