Verdict
The clearest difference is ads: Timer tick at none against UD Color Checker's shown. Timer tick also leads on update cadence (every 3 weeks vs every 2 months). UD Color Checker's advantage is iOS requirement (8.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.
