# Fault Current Calculator (PFC) vs Electrician Pro

The clearest difference is in-app purchases: Fault Current Calculator (PFC) at none against Electrician Pro's 1. Fault Current Calculator (PFC) also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.0). Electrician Pro's advantage is ads (none vs shown). On price there is nothing between them.

Both are free to download. Electrician Pro sells 1 one-off in-app purchase. Fault Current Calculator (PFC) asks for nothing beyond the download.
