# 返利APP vs 单词鸭

The clearest difference is rating: 单词鸭 at 4.8 against 返利APP's 4.0. 单词鸭 also leads on update cadence (every 2 weeks vs every 6 weeks) and ratings volume (29 vs 4). 返利APP's advantage is in-app purchases (none vs 25) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. 单词鸭 sells 25 in-app purchases, starting at $14.99 per month. 返利APP asks for nothing beyond the download.

单词鸭 holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: 单词鸭 has 29 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of 返利APP's written reviews are positive against 68% of 单词鸭's, so the app with the better star average is not the one people write more warmly about.

返利APP ships an update every 6 weeks, 单词鸭 every 2 weeks. The most recent releases landed on October 16, 2026 and October 30, 2026 respectively.
