Sketch UI instantly on pen‑enabled devices like the Microsoft Surface

UiSketcher is a pen‑optimized UI sketching app designed for devices like the Microsoft Surface. It lets you add multiple device backgrounds in a single document, draw directly on the active device, and extend screens for scrollable content. Pens and highlighters can be customized, saved globally, and reused across projects. An asset library stores reusable elements for quick drag‑and‑drop, streamlining the early‑stage design workflow.
