Verdict
The clearest difference is in-app purchases: CSI Pro at none against CodeMaster's 3. CSI Pro also leads on iOS requirement (8.0 vs 16). CodeMaster's advantage is update cadence (monthly vs every 12 months) and chart position (#128 vs unranked). On price, ads and device support there is nothing between them.
