Verdict
The clearest difference is update cadence: IP Keypad Pro at every 2 months against InductorCalc's every 23 months. IP Keypad Pro also leads on chart position (#200 vs unranked). InductorCalc's advantage is review sentiment (100% vs 75%) and device support (3 vs 1). On ads, in-app purchases and monetization model there is nothing between them.
