# 知米背单词 vs 记单词

The clearest difference is ads: 知米背单词 at none against 记单词's shown. 知米背单词 also leads on update cadence (every 5 weeks vs every 9 months) and ratings volume (460 vs 2). 记单词's advantage is rating (5.0 vs 4.8). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. 知米背单词 sells 12 one-off in-app purchases and 记单词 sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

记单词 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 知米背单词 has 460 ratings behind it against 2, so its average is the more settled of the two.

知米背单词 ships an update every 5 weeks, 记单词 every 9 months. The most recent releases landed on August 12, 2026 and September 25, 2026 respectively.
