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.
Great
Gavin Burn
Ive had the app for a while now and its definitely come a long way and its looking great. I’m a journeyman electrician and the app has been very useful. The dev is also really great at responding to feedback and making improvements. Highly recommend, for less then a coffee its a great deal.

Happy to hear 😊
Stupid pop ups
Sparky952
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.
Developer Response
Dear Spark,The issue with rating popups have been addressed in the latest version.Thanks for pointing out this issue.with regards,V Pugazhenthi
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.
Developer Response
Dear Customer,We regret for the inconvenience.Kindly click on the "restore" button to unlock the in-App purchases. If that doesn't help you. contact us at contact.pugal.apps@gmail.comwith regards,V PUGAZHENTHI
• Fixed an issue where wire size calculation results were not displayed properly in dark mode.
