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.

Verdict
The clearest difference is ads: Instant Reader at none against Leaf's shown. Leaf's advantage is update cadence (every 2 days vs every 2 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
