Verdict

The call

The clearest difference is price: Circuit Simulator at Free against Arduino Modules Pro's $4.99. Circuit Simulator also leads on iOS requirement (15.3 vs 17.0). Arduino Modules Pro's advantage is in-app purchases (none vs 8) and chart position (#171 vs unranked). On update cadence, ads and device support there is nothing between them.
