# Focus Clock vs 单词鸭

The clearest difference is rating: 单词鸭 at 4.8 against Focus Clock's 4.1. 单词鸭 also leads on monetization model (free with in-app purchases vs subscription). Focus Clock's advantage is ads (none vs shown) and review sentiment (83% vs 69%). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Focus Clock sells 3 in-app purchases, starting at $0.99 per 3 months and 单词鸭 sells 25 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

单词鸭 holds the better App Store score, 4.8 against 4.1. Both are backed by a comparable volume of ratings — 16 and 29 respectively. Written reviews complicate that: 83% of Focus Clock's written reviews are positive against 69% of 单词鸭's, so the app with the better star average is not the one people write more warmly about.

Focus Clock ships an update fortnightly, 单词鸭 every 3 weeks. The most recent releases landed on September 1, 2026 and September 26, 2026 respectively.
