Designing for foldable screens requires handling split layouts, hinge gaps, and dynamic orientation changes. Current solutions involve manual media queries and workarounds.
A framework could abstract these complexities with reusable components for common foldable patterns like spanned apps, dual-pane layouts, and adaptive toolbars.
Paid by agencies and product teams adopting foldables who want to save development time. Also sell premium templates for specific device models.
Start with a small open-source core for basic spanning behaviors, then monetize advanced features and tooling.
Risk: Foldables remain a niche market, or native OS solutions eventually cover most use cases.
