ChapterUp is a reading tracker that turns the books you read into XP, streaks, and ranks. Log every session with a built-in timer, hit a daily goal, and climb from Bronze to Master on the hours you put in. Download ChapterUp and log your first session tonight. Reading Tracker | Session Timer | Streaks | XP and Ranks | Reading Stats | Book Clubs Turn Reading Into a Habit You Can See Track Every Session Your bookshelf and your reading time sit side by side. Add a book once, and every session you read of it stacks up underneath it. - Session Timer: Start it when you open the book, stop it when you close it, and the session logs itself. - Your Library: Keep what you're reading and what you've finished on one shelf, and log your page as you go. Build a Daily Reading Habit Slumps rarely start with a bad book. They start with three days off, and a daily goal is how you keep day three from happening. - Daily Goal Ring: Set a target you can hit on a busy day and watch the ring close as you read. - Streaks and Achievements: Read every day and your streak grows; hit a milestone and it unlocks with animation, sound, and haptics from Tales, the ChapterUp cat. Level Up as You Read Every minute you log earns XP toward your next level, so a quiet twenty minutes still counts. - Levels: XP is earned from logged reading time, so levels track hours, not taps. - Ranks: Move from Bronze to Silver, Gold, Platinum, Diamond, and Master as your logged hours add up. See How You Actually Read Every session adds to a picture of how you read, not just what you finished. - Reading Stats: Time logged, sessions, books finished, pages per minute, average focus session, and average time to finish a book. - Heatmap and Pace: A reading-day heatmap shows every day you showed up, with an estimate of how far you are from your next rank. Read the Classics Inside the App ChapterUp Pro includes a library of classic works in the public domain, readable in full inside the app. Every page you read there counts toward your XP, streak, and daily goal. - One App, Not Two: Open a classic, hit start, and the session logs itself. No second reader, no page numbers to type in. - What Pro Includes: The classics library, advanced stats, the four immersive themes, and the cosmetic sets, with a 7-day free trial for new subscribers. Find Your Next Book The hard part of a TBR pile isn't the size; it's the picking. Discover sorts a rotating selection into shelves you already browse. - By Genre: Fantasy, Romance, Sci-Fi, Mystery, Thriller, Horror, Historical Fiction, YA, Biography, and Self-Help. - Refreshed Weekly: The shelves move on while you read, so something new is waiting when you finish. Make the App Yours The app should look like the book you're in, not like a spreadsheet. - Immersive Themes: Medieval, Dark Academia, Celestial, and Enchanted Forest reskin the whole app, not one accent color. - Cosmetics: Shelf themes, profile frames, rank cards, and outfits for Tales. Read Alongside Other People Most reading happens alone. Clubs and the feed are there for the parts that are better shared, and both are optional. - Book Clubs: Create a club for a book, invite friends with a link, and read it together at your own pace. - Your Feed: Post finished books and session recaps to a public feed or keep it friends-only, and report or block anyone at any time. Start Reading Today Pick the book you stalled on, press start, and let ChapterUp keep the count. Log one session and the streak starts at one. Tales will be waiting on the home screen.
