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.

Dear Jim,
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.

Stupid pop ups

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.

Dear Spark,

The issue with rating popups have been addressed in the latest version.Thanks for pointing out this issue.
with regards,
