Verdict

The call

The clearest difference is rating: Crossword Puzzle Redstone at 4.8 against Syntaxle's 4.0. Crossword Puzzle Redstone also leads on ratings volume (116K vs 1) and chart position (#146 vs unranked). Syntaxle's advantage is review sentiment (100% vs 58%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Crossword Puzzle Redstone holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Crossword Puzzle Redstone has 116K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 58% of Crossword Puzzle Redstone's written reviews are positive against 100% of Syntaxle's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Crossword Puzzle Redstone ships an update every 2 months, Syntaxle every 4 months. The most recent releases landed on October 21, 2026 and October 7, 2026 respectively.
