Verdict

The call

The clearest difference is ratings volume: Clozemaster-Vocabulary Builder at 2.1K against Readlang Language Readers's 5. Clozemaster-Vocabulary Builder also leads on rating (4.8 vs 4.6) and iOS requirement (16.4 vs 18.0). Readlang Language Readers's advantage is review sentiment (100% vs 83%) and update cadence (every 5 days vs every 11 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Clozemaster-Vocabulary Builder sells 8 in-app purchases, starting at $8.99 per month and Readlang Language Readers sells 3 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Clozemaster-Vocabulary Builder holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Clozemaster-Vocabulary Builder has 2.1K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 83% of Clozemaster-Vocabulary Builder's written reviews are positive against 100% of Readlang Language Readers's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Clozemaster-Vocabulary Builder ships an update every 11 days, Readlang Language Readers every 5 days. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
