Verdict

The call

The clearest difference is update cadence: Electronic Component Codes Pro at every 7 months against Fundamental RLC's every 38 months. Electronic Component Codes Pro also leads on iOS requirement (16.0 vs 18.0). Fundamental RLC's advantage is price ($0.99 vs $3.99) and chart position (#197 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
