ReceptionRating · Positive reviews · Number of ratings

Fluency Drop holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 64 and 38 respectively. Written reviews complicate that: 64% of ReadLang WatchLang's written reviews are positive against 63% of Fluency Drop's, so the app with the better star average is not the one people write more warmly about.
