ReceptionRating · Positive reviews · Number of ratings

ElectriCalc Pro holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: ElectriCalc Pro has 354 ratings behind it against 68, so its average is the more settled of the two. Written reviews complicate that: 78% of ElectriCalc Pro's written reviews are positive against 86% of Electrical Toolkit by HCP's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ElectriCalc Pro ships an update every 10 months, Electrical Toolkit by HCP every 8 days. The most recent releases landed on September 19, 2026 and September 24, 2026 respectively.
