Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Crossword Puzzle Redstone sells 13 one-off in-app purchases and Syntaxle sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
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.
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.
