# 答案之书 vs 八字排盘

The clearest difference is ads: 八字排盘 at none against 答案之书's shown. 八字排盘 also leads on update cadence (every 2 months vs every 10 months) and rating (4.8 vs 4.5). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. 答案之书 sells 1 one-off in-app purchase and 八字排盘 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

八字排盘 holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: 八字排盘 has 33 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 86% of 答案之书's written reviews are positive against 90% of 八字排盘's.

答案之书 ships an update every 10 months, 八字排盘 every 2 months. The most recent releases landed on September 17, 2026 and September 20, 2026 respectively.
