# Jade Codex vs 卦记

The clearest difference is update cadence: 卦记 at every 3 days against Jade Codex's every 11 days. 卦记 also leads on iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Jade Codex sells 2 in-app purchases, starting at $4.99 per month and 卦记 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Jade Codex ships an update every 11 days, 卦记 every 3 days. The most recent releases landed on September 10, 2026 and August 9, 2026 respectively.
