About this app

Lumen is a calm reader for people who want their books, highlights, and notes in one place.

Build a focused EPUB library, keep track of what you are reading, and create notebooks for the ideas that come up along the way. Lumen is designed to feel quiet, organized, and ready for long reading sessions.

What you can do with Lumen:

• Read EPUB books in a clean, distraction-free interface
• Organize your library with shelves and reading progress
• Highlight passages and keep notes connected to your books
• Create standalone notebooks for reading journals, quotes, and ideas
• Write on a clean Android canvas with stylus-ready notebook tools
• Track reading goals, streaks, and reading stats

Lumen is built for readers who annotate, study, journal, and think while they read. Your library becomes more than a shelf — it becomes a workspace for your reading life.
