Verdict

The call

The clearest difference is rating: PMI View at 5.0 against Fault Current Calculator's 3.1. PMI View also leads on in-app purchases (none vs 2) and update cadence (every 2 months vs every 4 months). Fault Current Calculator's advantage is ratings volume (23 vs 4) and iOS requirement (14.0 vs 18.0). On price, ads and device support there is nothing between them.
