# CodeAB vs Clue Master

The clearest difference is review sentiment: CodeAB at 100% against Clue Master's 27%. CodeAB also leads on ads (none vs shown) and rating (5.0 vs 4.6). Clue Master's advantage is ratings volume (28K vs 3) and update cadence (every 3 weeks vs every 6 weeks). On price, in-app purchases and device support there is nothing between them.

Both are free to download. CodeAB sells 1 one-off in-app purchase and Clue Master sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CodeAB holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Clue Master has 28K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of CodeAB's written reviews are positive against 27% of Clue Master's.

CodeAB ships an update every 6 weeks, Clue Master every 3 weeks. The most recent releases landed on October 21, 2026 and November 3, 2026 respectively.
