Verdict

The call

The clearest difference is rating: Knowt at 4.7 against SAT Wordrush's 4.2. Knowt also leads on ratings volume (11K vs 5) and chart position (#128 vs unranked). SAT Wordrush's advantage is in-app purchases (none vs 10). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Knowt sells 9 in-app purchases, starting at $9.99 per 7 days. SAT Wordrush asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Knowt holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Knowt has 11K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 62% of Knowt's written reviews are positive against 67% of SAT Wordrush's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Knowt ships an update weekly, SAT Wordrush every 2 weeks. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
