# HookBook vs Patterns

The clearest difference is in-app purchases: Patterns at none against HookBook's 5. Patterns also leads on update cadence (every 4 days vs every 3 weeks). HookBook's advantage is ratings volume (325 vs 1). On price, rating, ads and device support there is nothing between them.

Both are free to download. HookBook sells 5 in-app purchases, starting at $6.99 per month. Patterns asks for nothing beyond the download.

Patterns holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HookBook has 325 ratings behind it against 1, so its average is the more settled of the two.

HookBook ships an update every 3 weeks, Patterns every 4 days. The most recent releases landed on November 3, 2026 and November 1, 2026 respectively.
