Designing for iPhone Duo, right from the iPad. ✍🏻

Been working on bringing the new iPhone Duo frames and interface elements to @MockupApp, so you can start exploring ideas for both displays.

Coming soon. 👀

Design in landscape on iPhone. 📱

Mockup 4.4 brings a more flexible iPhone experience, so your canvas can adapt to the way you hold your device.

Use Mockup in landscape, resize it on Mac with iPhone Mirroring, and design with a workspace that fits your screen.

Another major Apple update, another special milestone for Mockup.

This fall, we updated on day one for iOS 27 and macOS 27, brought in the new design, and added Image Playground inside the app.

Seeing Mockup featured across the App Store for this release means a lot. 💜

Walked into the Apple Store, and there it was.
@MockupApp, featured as a demo app.

Seeing it like this hits different.

What started as an idea on my desk didn’t just make it to the App Store… It’s now running in Apple Stores around the world.

Incredibly grateful!
