# WriterAI vs Book Creator

The clearest difference is update cadence: Book Creator at every 5 weeks against WriterAI's every 15 months. WriterAI's advantage is iOS requirement (11.0 vs 17.2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. WriterAI sells 1 in-app purchase, starting at $1.99 per 7 days and Book Creator sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

WriterAI ships an update every 15 months, Book Creator every 5 weeks. Both last shipped on October 25, 2026.
