For app teams · Work with iPhone Duo Apps

Build a better app
for iPhone Duo.

Redesign the interface. Add a useful workflow. Make the extra space count, from the first review to a scoped Duo conversion.

Duo app conversion

Make Duo your app’s best experience.

We help existing iOS apps use the larger workspace well, with a redesigned interface and an agreed new feature. Start with a prototype, then scope the full build.

What a readiness review means

Request a sample report

The review uses the public documentation and testing environments available at the time of the engagement. Simulator findings are identified as simulator findings. Hardware-dependent behavior remains unverified until it is tested on the device.

This is a preparation service. It does not provide Apple certification, guarantee App Store approval, or promise support for undocumented APIs. Device testing is scoped separately after hardware becomes available.

Apple’s product page lists availability from October 23. That leaves time to find fragile layouts and expensive assumptions before launch.
