Verdict
The clearest difference is in-app purchases: Electronic Component Codes at none against RC Circuit's 1. Electronic Component Codes also leads on update cadence (every 6 weeks vs every 6 months). RC Circuit's advantage is ads (none vs shown) and iOS requirement (12.0 vs 16.0). On price and device support there is nothing between them.
