# 知米背单词 vs 生词本

知米背单词 and 生词本 both sit at 4.8 stars, but that hides the real split: 97% of 知米背单词's written reviews are positive against 81% of 生词本's. 知米背单词 also leads on iOS requirement (9.0 vs 12.0). 生词本's advantage is update cadence (fortnightly vs every 5 weeks) and ratings volume (2.6K vs 460). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. 知米背单词 sells 12 one-off in-app purchases and 生词本 sells 3 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for 知米背单词 against 4.8 for 生词本. That said, the two scores are not equally well evidenced: 生词本 has 2.6K ratings behind it against 460, so its average is the more settled of the two. Written reviews are what separate them: 97% of 知米背单词's written reviews are positive against 81% of 生词本's.

知米背单词 ships an update every 5 weeks, 生词本 fortnightly. The most recent releases landed on August 12, 2026 and September 24, 2026 respectively.
