Luku: Book & Reading Tracker
Track library, time & goals
Free
Luku is a personal reading tracker for people who care about building a consistent reading habit. Track your books, set goals, time your sessions, and see your progress over time.
READING TIMER
Start a timer when you sit down to read. Luku shows your session on the lock screen and Dynamic Island as a Live Activity, so you can check your time without unlocking your phone. The timer keeps running when your screen is off.
TRACK ANY FORMAT
Track pages for physical books, percentage for e-books, or time listened for audiobooks. Update your progress after each session or manually anytime. Luku calculates your reading pace automatically.
DAILY & YEARLY GOALS
Set a daily reading goal in minutes and a yearly goal in books. See your progress on a goal ring that fills as you read. Hit your goal and celebrate with confetti.
STREAKS
Build a reading streak by reading every day. Luku tracks your current streak and motivates you to keep going.
STATS & INSIGHTS
See your weekly reading chart, daily pace, reading speed, and monthly calendar showing which days you read. Track how many books you've finished this year toward your goal.
YOUR LIBRARY
Organize books by status: Reading, To Read, Finished, and Abandoned. Search and add books instantly. Add notes, bookmarks, and ratings to any book.
WORKS OFFLINE
Luku works without internet. Your library loads instantly from local storage. Sessions and progress updates save locally and sync automatically when you're back online.
SEAMLESS SYNC WITH LUKU.APP
Use the same account on luku.app (web) and the iOS app. Your books, sessions, goals, and progress stay in sync across all your devices.
SIGN IN WITH APPLE OR GOOGLE
Create an account or sign in with Apple, Google, or email. Link multiple sign-in methods in settings.
API & MCP
Everything the web app and the iOS app can do, over HTTP or through Claude. Your reading is yours: read it, write it, back it up, take it elsewhere.
