Verdict
The clearest difference is in-app purchases: Mastermind Timer at none against Curieous's 5. Mastermind Timer also leads on ads (none vs shown). Curieous's advantage is update cadence (every 4 days vs every 5 weeks) and iOS requirement (12.4 vs 16.4). On price and device support there is nothing between them.
