"I keep buying books — but never find time to read them." You're not alone. Nearly 70% of people feel they don't read enough. But the problem isn't willpower. It's visibility. When you can't see your reading time, building a habit is almost impossible. Reading Time Log tracks your reading with a single tap. When the numbers start adding up, reading stops feeling like effort — and starts becoming routine. 【What Changes When You Use It】 • See exactly how many books you've read this year • Build a daily reading streak — and actually want to keep it going • Add unread books to your list — never forget what to read next • Track in the background — lock your phone while you read 【Simple Enough to Actually Stick】 Tap start. Read. Tap stop. No reviews, no notes, no setup. Zero friction. Book-tracking apps don't have a timer. Generic habit apps aren't built for reading. Reading Time Log fills that gap. "30-day streak. I started reading just 5 minutes some nights because I didn't want to break it." "3 months in — I'd finished 15 books without realizing. I was genuinely surprised." "15 minutes before bed. By the end of the year, that was 36 books." That could be you. 【Common Questions】 "Won't tracking become the point?" — Tap the timer, then just read. No reviews, no notes. The point is building the reading habit — not the tracking itself. "I already use a habit timer for reading. What's different?" — A general timer tracks hours. Reading Time Log tracks which book you spent those hours on. At year's end, you don't just see how many hours — you see exactly what you read. "I always quit reading apps after a week." — The streak changes that. You'll read 5 minutes just to keep it alive. That's the mechanism. "Is it free?" — Reading logs, streaks, and stats are all free. Premium unlocks more. Price shown before you commit. "Will my data disappear?" — All reading data is stored safely on your device. No personal information is collected.

One tap — and your unread shelf starts shrinking. 【From the Growth & Learning Series — Related Apps】 - Quest Goal: Set reading goals and track them like a game - Archly: Save articles and links you find while reading Search each app name on the App Store.
