Comments on Electrical Calculations for Android

★★★★★ 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.

★★★★☆ Nadeem Qurashi · Aug 5, 2025

Please include all the calculations for three-phase power and distribution transformers as well as for motors, thanks.

★☆☆☆☆ MOMIN UMAIR · Mar 4, 2025

Very Poor not give proper calculation Don't install this aap

★☆☆☆☆ Luis Deutsch · Aug 13, 2026

They switched from a pay once to a yearly subscription scheme, and that's something I'll never go for. I have a license of the pay-once version from some time ago, and although I should be entitled to install it on a replacement phone, the app now asks for yearly subscriptions. It is ok to pay once for an (otherwise pretty useful) app, but I'm not going to subscribe to perpetually leaking fees. What a pity.

★★☆☆☆ 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.

★☆☆☆☆ 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.

★☆☆☆☆ 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
