# Reading Tracker vs Book

The clearest difference is ads: Reading Tracker at none against Book's shown. Reading Tracker also leads on update cadence (every 9 days vs every 6 months). Book's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18.2). On price and in-app purchases there is nothing between them.

Both are free to download. Reading Tracker sells 4 in-app purchases, starting at $3.99 per month and Book sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Reading Tracker ships an update every 9 days, Book every 6 months. The most recent releases landed on October 2, 2026 and September 24, 2026 respectively.
