Verdict
The clearest difference is in-app purchases: Peroz at none against Zero's 10. Peroz also leads on iOS requirement (15.1 vs 17.0). Zero's advantage is update cadence (every 2 weeks vs every 6 weeks) and chart position (#102 vs unranked). On price, ads and device support there is nothing between them.
