Free basic calculations for EV owners and a whole lot more!
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.
Developer Response ,
We will accommodate the features, you asked for, in our next update.
Neat little tool
If you work with relays or any electrical circuits this is a real time saver. Sure all of us know ohm's law, but it seems like we usually need to take the time to figure what gets divided by what to get the result. This does all the work in seconds and can do a wide variety of different calculations.
Paid but not unlocked - no response
I downloaded this application to my Ipad 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.
