Verdict
The clearest difference is price: EV CALC at Free against Kilowatt's $2.99. EV CALC also leads on iOS requirement (11.0 vs 26.0). Kilowatt's advantage is rating (4.4 vs 4.0) and ratings volume (18 vs 1). On review sentiment, update cadence, ads and in-app purchases 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
EV CALC is free to download; Kilowatt costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Kilowatt holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Kilowatt has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 81% of Kilowatt's written reviews are positive against 88% of EV CALC's, so the app with the better star average is not the one people write more warmly about.
Kilowatt ships an update monthly, EV CALC every 3 weeks. Both last shipped on November 3, 2026.
