About the Online Course App
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.
What's inside
Screens included
Home
A "Welcome back" greeting with a large current-module card showing the lesson, 62% completion, minutes left, and a cobalt progress bar, plus a horizontal row of recommended courses with illustrated thumbnails and durations. The resume-where-you-left-off entry point.
Catalog
An "Explore Knowledge" header with a search field, topic filter chips like Design, Coding, and Business, and course cards carrying flat-illustrated covers, star ratings, lesson counts, and total hours. The browse-and-discover surface.
Course detail
An illustrated hero with the module eyebrow and slab-serif title, an instructor row with portrait and credentials, Syllabus, Overview, and Reviews tabs, and a cobalt "Resume Learning" button. Where learners decide and dive in.
Lesson player
A 16:9 video frame with a scrubber and timestamps, the lesson eyebrow and title, Notes, Resources, and Discussions tabs with a highlighted key insight, and Prev, Mark Complete, and Next controls. The core study screen.
Your Progress
A hero hours-invested number, a weekly study-streak row with sage checkmarks and a cobalt flame for today, and a "My Courses" list with per-course progress bars and completion states. Keeps learners motivated and on track.
