Comments on Electrical Calculations for Android

★★★★☆ Nadeem Qurashi · Aug 5, 2025
Please include all the calculations for three-phase power and distribution transformers as well as for motors, thanks.
★★★★★ Dave Tuck · Mar 29, 2025
The most useful app for electrical wiring! I'm wiring a battery system for 4wd batteries, lights, inverter, air and water pumps, solar panels, DC-DC charger and mppt charger. Look no further for an app that does wire size, voltage drop, resistance etc. etc. etc. Gold!
★★★★★ Wayne Carter · Jun 21, 2025
Very complicated for an amature doing basic car and boat wiring but just focusing on wire size NEC calculator is such a useful tool to have.
★☆☆☆☆ Devang · Nov 1, 2025
Ads pop up right on clicking Calculate. I understand that a developer needs to cover costs, but this is ridiculous. Just a couple of years ago the app was $14.99 lifetime compared to $42.99 now. How much greed do you guys have? Update after Response: So you're telling me that $6/yr is cheaper than $14.99 lifetime from couple years ago cheaper? If I were to use an app for 20 years then 20x6 $120 (if you don't jack up prices) is cheaper than $15 lifetime? Greedy much.
★☆☆☆☆ MOMIN UMAIR · Mar 4, 2025
Very Poor not give proper calculation Don't install this aap
★★☆☆☆ Electrifying Services LLC · May 23, 2025
Looks like there's a lot of things in the app, but it did not do what I needed. Defaults to metric and even after changing it to imperial in the setting the drop-downs were still in metric. Not sure who this is for.
★☆☆☆☆ Martin Axelsen · Oct 13, 2025
Most formulas are locked away behind a paywall. Instant uninstallation Reply: I'd rather have all formulas along with commercials
