# 奇门遁甲 vs 此八子

The clearest difference is review sentiment: 奇门遁甲 at 97% against 此八子's 50%. 奇门遁甲 also leads on rating (4.5 vs 3.3) and ratings volume (17 vs 3). 此八子's advantage is update cadence (every 5 days vs every 6 weeks) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 奇门遁甲 sells 2 one-off in-app purchases and 此八子 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

奇门遁甲 holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: 奇门遁甲 has 17 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 97% of 奇门遁甲's written reviews are positive against 50% of 此八子's.

奇门遁甲 ships an update every 6 weeks, 此八子 every 5 days. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
