# Chapter vs BookSafe

The clearest difference is iOS requirement: BookSafe at 18.0 against Chapter's 26.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Chapter sells 3 in-app purchases, starting at $1.99 per month and BookSafe sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Chapter ships an update every 2 weeks, BookSafe weekly. The most recent releases landed on October 28, 2026 and October 29, 2026 respectively.
