Ohms Law Calc. for Android

This app is not worth the $4. I have been in the electrical trade for over 25 years and can do the math on my own but thought this would make quick work of calcs, but the more I play with it the more I get puzzled. I would not recommend buying this if you live in the US.

I downloaded this application to my Mobile because it looked very useful. I paid the $3.99 immediately Days later It is still locked and I can’t get any response from them via email. Because of their lack of response and the fact that it has ads and offers I don’t consider this a functional product that I can recommend.

This app is fine for basic current and power calculations an electric car driver may need to figure recharging times. They are free along with voltage and power calculations. But I needed more: voltage drop over a 50 foot Extention cord that the EV charger is connected to. For a few dollars more, that is available plus a whole host of other calculations. Then there is the conversion side, which I do not use. You get Field Strength, Electrical Potential and Resistance for free but must pay a dollar to unlock the rest. Whether EV driver or dabbling in electronics, this may be the app for which you have been looking.

I just payed for all 49 calculators. From the first time I used it, this rate me window popped up EVERY TIME I tried to use it. How can I rate it if I haven’t used it? Otherwise I would have given a fair rating in a few days.

Rated 1 star because after paying it asks you to rate with every window change and every calculation.
