# CodeMaster vs Quack

The clearest difference is review sentiment: Quack at 100% against CodeMaster's 44%. Quack also leads on monetization model (free with in-app purchases vs subscription). CodeMaster's advantage is rating (4.6 vs 4.0) and ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. CodeMaster sells 3 in-app purchases, starting at $1.99 per 7 days and Quack sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CodeMaster holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: CodeMaster has 140 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 44% of CodeMaster's written reviews are positive against 100% of Quack's, so the app with the better star average is not the one people write more warmly about.

CodeMaster ships an update monthly, Quack every 6 weeks. The most recent releases landed on October 10, 2026 and September 22, 2026 respectively.
