Verdict

The call

The clearest difference is price: CodeMaster at Free against UCoW's $3.99. CodeMaster also leads on rating (4.6 vs 3.8) and ratings volume (140 vs 12). UCoW's advantage is in-app purchases (none vs 3) and chart position (#132 vs unranked). On update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

CodeMaster holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: CodeMaster has 140 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 44% of CodeMaster's written reviews are positive against 54% of UCoW's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CodeMaster ships an update monthly, UCoW every 3 weeks. The most recent releases landed on October 10, 2026 and October 14, 2026 respectively.
