# Chapter vs ReadXP

The clearest difference is iOS requirement: ReadXP at 16.0 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 ReadXP sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Chapter ships an update fortnightly, ReadXP every 9 days. The most recent releases landed on October 24, 2026 and October 13, 2026 respectively.
