Verdict
The clearest difference is rating: CodeMaster at 4.6 against PotoHEX's 3.5. CodeMaster also leads on ratings volume (140 vs 16) and review sentiment (44% vs 33%). PotoHEX's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 2 weeks vs monthly). On price, ads, in-app purchases and device support there is nothing between them.

Written reviews point the same way: 44% of CodeMaster's written reviews are positive against 33% of PotoHEX's.
CodeMaster ships an update monthly, PotoHEX every 2 weeks. Both last shipped on October 19, 2026.
