Leaf vs Koob

Stop starting books you never finish. Leaf turns reading into a daily habit. Without the guilt. Track progress page by page, set a daily goal, and build the streak that keeps you reading. Or set a reading challenge: pick a few books, pick a finish date, and Leaf tells you how many pages to read each day. The first reading tracker connected to your AI assistant (Pro). READING STREAKS Build a consistent reading habit: - Daily streak counter with a weekly reading calendar - 3-hour grace period for late-night reading sessions - Missed a day? One tap to backdate yesterday's reading. No guilt, no penalty - Nine milestone levels from Sprout to Ancient, earned permanently even if your streak resets DUAL GOAL-SETTING MODES Choose the approach that fits your style: - Flexible Mode - set pages per day, Leaf calculates your finish date "I want to read 20 pages daily" - Fixed Date Mode - set a target date, Leaf calculates daily pages "I want to finish by March 15" READING CHALLENGES "5 books in 3 months." Leaf does the math. - Pick your books, pick a finish date - Leaf tells you how many pages to read today - Read extra today, and tomorrow's number goes down - Fall behind, and the number just updates. No penalty - Every week, an email and a notification with how you're doing - Finish, and get a recap you can share Reading challenges come with the Challenge Pass (3 months) or Leaf Pro. It's private. Just you and your books, no leaderboard.

The library that works anywhere — and pays you back. Koob is a book catalog built by the people who read from it. Organize the books you own, track everything you read, and earn your way through the app by making the catalog better for everyone after you. It all runs on your device, so it keeps working with no signal at all. BUILT TO WORK OFFLINE Your whole library lives on your phone — every shelf, note, cover, and reading session. No signal on the metro, in the stacks, or on a plane? Your shelves glow on. Browse, edit, shelve, take notes, and log your reading exactly as you always do. Everything you change offline queues up quietly and syncs itself the moment you're back. A CATALOG BUILT BY READERS Scan a barcode and the book is yours — cover, author, and details filled in automatically. And when a book isn't in the catalog yet, you don't hit a dead end: add it yourself. Scan the spine, snap the cover, fill in what you know. Once a reviewer accepts it, that book is in the catalog for good, and every reader who comes looking for it finds it because of you. EARN TOKENS FOR EVERY CONTRIBUTION Accepted books earn tokens, with a bonus for adding a spine photo. Fix a typo, add a missing cover, complete an entry — the work you put into the catalog comes back to you. Prefer not to contribute? You can earn free tokens daily, and Premium members get a monthly allowance. SPEND THEM ON WHAT YOU NEED Tokens unlock Super Search, which digs past our shelves into an extended database to find the rare editions and obscure printings. Or put them toward Koob+ premium months. Contribute enough and the app pays for itself. COLLECT THE STAMP ALBUM Your milestones aren't a checklist — they're issued as stamps in a real collector's album, one series to a page. Each series climbs from bronze through silver, gold, and platinum to diamond, and you can watch the next tier ink in as you read toward it. Premium unlocks special series for your books, your genres, and your bookcases. ORGANIZE YOUR WAY Create custom bookcases and shelves that mirror your real-life setup. Arrange books exactly how you want them and find any title at a glance. TRACK YOUR READING Set goals by books or by pages, log your reading sessions, and watch your progress build through the year. Your reading statistics show you exactly where you stand. TAKE PERSONAL NOTES Jot down thoughts, favorite quotes, or reflections for any book. Your notes stay private and stay with you, online or off. READ ON EVERY DEVICE Go Premium to sync your library across all your devices, so the collection you build on one is waiting on the next. Every book you add helps the next reader. Start building with Koob. Terms of Use (EULA): https://ko-ob.ro/mobile/en/terms-and-conditions/ Privacy Policy: https://ko-ob.ro/mobile/en/privacy-policy/
