# 背记佳 vs 问真八字

The clearest difference is rating: 背记佳 at 4.9 against 问真八字's 3.8. 背记佳 also leads on iOS requirement (11.0 vs 15.0). 问真八字's advantage is ads (none vs shown) and update cadence (monthly vs every 2 months). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. 背记佳 sells 1 one-off in-app purchase and 问真八字 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

背记佳 holds the better App Store score, 4.9 against 3.8. Both are backed by a comparable volume of ratings — 14 and 57 respectively. Written reviews complicate that: 86% of 背记佳's written reviews are positive against 89% of 问真八字's, so the app with the better star average is not the one people write more warmly about.

背记佳 ships an update every 2 months, 问真八字 monthly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
