Verdict
The clearest difference is in-app purchases: Circuit Resistance Creator at none against Resistor Tools's 1. Circuit Resistance Creator also leads on review sentiment (100% vs 75%) and update cadence (every 3 weeks vs every 2 months). Resistor Tools's advantage is ratings volume (10 vs 3) and iOS requirement (12.0 vs 14.0). On price, rating, ads and device support there is nothing between them.
