Verdict
The clearest difference is price: CertWarden at Free against iDevTools's $0.99. CertWarden also leads on update cadence (daily vs every 3 months). iDevTools's advantage is in-app purchases (none vs 1) and chart position (#123 vs unranked). On ads, device support and iOS requirement there is nothing between them.
