Micro-apps · local-first

Small applications that keep useful state.

These releases go beyond one-shot calculators: they support multi-step workflows, browser-local persistence, explicit recovery, portable JSON and deterministic version migration. No account or cloud sync is required.

What stays on your device

App state is stored locally in the browser. Export creates a JSON file on your device; import reads a file you explicitly choose. ICU does not create an account, remote profile, order record or provider connection for these apps.

Interactive knowledge companion

Color, Light and Perception Lab

Explore 16 source-grounded demonstrations of reflection, transmission, illumination, display limits and visual perception, with reproducible local settings and explicit screen-approximation boundaries.
