# 不背单词 vs Chimp Test

The clearest difference is ads: 不背单词 at none against Chimp Test's shown. 不背单词 also leads on ratings volume (3.6K vs 2) and review sentiment (94% vs 71%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. 不背单词 sells 10 one-off in-app purchases and Chimp Test sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Chimp Test holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 不背单词 has 3.6K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 94% of 不背单词's written reviews are positive against 71% of Chimp Test's, so the app with the better star average is not the one people write more warmly about.

不背单词 ships an update every 3 weeks, Chimp Test every 5 weeks. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
