Verdict
The clearest difference is monetization model: PED at free with in-app purchases against Certa Dose's subscription. Certa Dose's advantage is update cadence (every 3 months vs every 10 months) and iOS requirement (13.0 vs 15.1). On price, rating, ratings volume and ads there is nothing between them.
