Verdict

The call

The clearest difference is in-app purchases: kVA Calculator at none against Electrical Calculator lite's 2. kVA Calculator also leads on iOS requirement (15.0 vs 17.6). Electrical Calculator lite's advantage is ads (none vs shown) and ratings volume (578 vs 12). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. Electrical Calculator lite sells 2 one-off in-app purchases. kVA Calculator asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Electrical Calculator lite holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Electrical Calculator lite has 578 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 42% of kVA Calculator's written reviews are positive against 39% of Electrical Calculator lite's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

kVA Calculator ships an update every 6 months, Electrical Calculator lite every 2 months. Both last shipped on October 24, 2026.
