The easiest way to actually finish books: ten leaves a day. Leaf by Leaf is a reading-habit app built around one small ritual — read ten leaves (about 20 pages) and keep one line that stayed with you. No long reviews. One line is enough. HOW IT WORKS • Snap today's pages — text is recognized right on your device • Pick the line that stayed with you, and today is logged • 18+ pages counts as a full day — fewer still keeps your log • Keep going and watch your streak grow • Your day follows your own time zone, and you choose when it ends READING TOGETHER MAKES IT LAST • Start a reading group and invite friends with one link • Read the same book together: see each other's progress, with lines from pages ahead of you hidden — no spoilers • Follow friends and see their lines in your feed • Cheer each other on with likes and comments • See which lines other readers chose from the same book YOUR LOG BECOMES YOUR READING JOURNAL • Per-book progress, finished books, monthly recap • Every line you keep builds your own reading journal SHARE ONE LINE AS A CARD • Turn a line, the book title, and your streak into a card and share it PRIVACY FIRST • Page photos are read on your device only — never uploaded • Delete your account in the app at any time — everything is removed immediately
