# WireSizer vs ElectriCalc Pro

The clearest difference is price: ElectriCalc Pro at Free against WireSizer's $4.99. ElectriCalc Pro also leads on rating (4.9 vs 4.5) and iOS requirement (14.0 vs 26.0). WireSizer's advantage is in-app purchases (none vs 2) and update cadence (every 5 months vs every 10 months). On review sentiment, ratings volume, ads and device support there is nothing between them.

ElectriCalc Pro is free to download; WireSizer costs $4.99 up front. ElectriCalc Pro sells 2 in-app purchases, starting at $4.99 per month. WireSizer asks for nothing beyond the download.

ElectriCalc Pro holds the better App Store score, 4.9 against 4.5. Both are backed by a comparable volume of ratings — 226 and 354 respectively. Written reviews complicate that: 84% of WireSizer's written reviews are positive against 78% of ElectriCalc Pro's, so the app with the better star average is not the one people write more warmly about.

WireSizer ships an update every 5 months, ElectriCalc Pro every 10 months. The most recent releases landed on October 13, 2026 and October 11, 2026 respectively.
