Verdict
The clearest difference is price: EzBlock Studio at Free against InductorCalc's $0.99. EzBlock Studio also leads on update cadence (every 3 months vs every 23 months). InductorCalc's advantage is review sentiment (100% vs 91%). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
