Verdict
The clearest difference is in-app purchases: Concentric Neutral Calculator at none against Voltage Drop Calculator.'s 1. Concentric Neutral Calculator also leads on ads (none vs shown). Voltage Drop Calculator.'s advantage is update cadence (every 3 months vs every 7 months). On price, device support and iOS requirement there is nothing between them.
