Online Course App UI Design

Lumen is an online course app UI design built around a "Focused Scholar" look: a warm paper-white canvas, deep ink charcoal text, and a single confident cobalt accent reserved for progress fills and primary buttons. Surfaces sit on flat chalk-gray fills separated by hairline rules with no drop shadows, while a muted sage marks completed states. Sturdy slab-serif course titles pair with a precise neutral UI font, and large tabular numbers carry durations and progress percentages.

The template ships six connected screens that form a complete learning flow: a Home that resumes the current module, a searchable Catalog with topic filters, a Course detail with instructor and syllabus tabs, a Lesson player with notes and resources, a Progress screen with a study streak and hours learned, and a Profile with skills and certificates. A signature tracked-out eyebrow ("MODULE 03 · LESSON 12") sits above every title so the whole app reads like a well-structured textbook.

Use it in Sleek and make it yours: restyle the palette, edit any screen with AI by describing the change, and add the flows your course product needs. Then export it to code, copy it into Figma, or hand a prompt to an AI agent to build it for real, far faster than starting from a blank canvas.
