# 初中英语词汇合集 vs 知米背单词

The clearest difference is ads: 知米背单词 at none against 初中英语词汇合集's shown. 知米背单词 also leads on ratings volume (460 vs 4) 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. 初中英语词汇合集 sells 1 one-off in-app purchase and 知米背单词 sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

知米背单词 holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: 知米背单词 has 460 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of 初中英语词汇合集's written reviews are positive against 97% of 知米背单词's, so the app with the better star average is not the one people write more warmly about.

初中英语词汇合集 ships an update every 3 months, 知米背单词 every 5 weeks. The most recent releases landed on September 7, 2026 and August 12, 2026 respectively.
