Could you build this?
Partial The paint-and-fold interaction is a simple UI concept, but reading the fold angle on a foldable iPhone needs hinge-sensing APIs that may not be publicly exposed, and the realistic paint simulation takes specialized work.
What it would actually take: The app needs iOS hinge or fold-angle sensing, possibly through public motion or sensor APIs if they exist for the device. Realistic ink spreading and print rendering need a custom physics or fluid-style simulation in Metal or a similar graphics stack. Access to the device's fold-state API and graphics expertise are the main requirements.
