What would you use the two halves of iPhone Duo’s display for?

Hi!

LumaFold launches tomorrow.

After publishing more than ten apps in the App Store, I wanted to build something specifically around iPhone Duo’s foldable display, rather than just make another app for a larger screen.

LumaFold turns the two halves into a small creative light studio.

One half can show a live front-camera mirror while the other provides adjustable light for makeup or grooming.

Both halves can also create separate colors and animations, light an object while you film it with another camera, or simply provide a visual background while you listen to music.

I’m curious: what would you try first on iPhone Duo, a mirror with light, object lighting, animated colors, or something else?
