Verdict
The clearest difference is price: kVA Calculator at Free against Electrical Calculator's $3.99. kVA Calculator also leads on iOS requirement (15.0 vs 17.6). Electrical Calculator's advantage is ads (none vs shown) and ratings volume (462 vs 12). On rating, update cadence, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
kVA Calculator is free to download; Electrical Calculator costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Electrical Calculator holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Electrical Calculator has 462 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 42% of kVA Calculator's written reviews are positive against 53% of Electrical Calculator's.
kVA Calculator ships an update every 6 months, Electrical Calculator every 4 months. The most recent releases landed on October 24, 2026 and October 29, 2026 respectively.
