Verdict
The clearest difference is ads: Rubik's Clock at none against Quick Power Nap Timer's shown. Quick Power Nap Timer's advantage is update cadence (every 3 weeks vs every 10 months) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
