# Moai vs OpenBook

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

Both are free to download. Moai sells 1 in-app purchase, starting at $14.99 per month and OpenBook sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Moai ships an update monthly, OpenBook every 2 weeks. The most recent releases landed on October 30, 2026 and October 14, 2026 respectively.
