### 3/5 — I have purchased the app in the past and now I have to pay again ????

*2024-11-04*

App was purchased 2 years ago. They made an update recently and now I have to buy again the app that I have already purchased. This is stealing. This is fraud! Give me acces back to the app that I have already paid for.!!!!

**Developer response:** You can always unlock the App using the restore button on the top right corner of the List View. You need not pay again. This holds good, when you switch to a new device.
The App works on iPhones and iPads with that single payment.
If you have trouble in restoring , kindly contact us @ contact.pugal.apps@gmail.com

### 2/5 — Annoying

*2019-08-31*

I’ve purchased the unlocked content and parameters but still have adds and every time I try to access one of the unlocked areas I get prompted to buy now??? Sort this out or refund me please!!!

**Developer response:** Hi,

 If you have purchased the in-App, you can restore the same, by clicking on the restore button on the left corner of the table view.

with regards,

### 2/5 — Stupid pop ups

*2018-06-13*

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,

### 2/5 — Needs more work yet.

*2017-11-11*

Don’t buy the pack. Would not work after buying. Keeps shutting down.

But the free bit is ok.

### 1/5 — Worst Ohms calculator ever seen

*2017-04-06*

dont waste your time downloading it.

### 5/5 — Great Tool

*2016-10-17*

Great Tool when on the go and trouble shooting different issues

### 5/5 — Devendran mani

*2015-10-10*

Easy to use & covers a major part of electrical calculations

### 5/5 — Neat little tool

*2015-08-27*

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.

### 5/5 — Show!

*2015-07-16*

Muito bom,recomendo muito pra quem trabalha nesse área. 

Me salva sempre pra correção de fator de potência. ⚡️⚡️⚡️⚡️

### 4/5 — Bom

### 1/5 — No easy to use

*2024-08-29*

Just trying to calculator multiple resistors in parallel.  Thought I used to be able to use this app.  Could figure it out now.  Went to web based calculator which was much easier.

**Developer response:** The App has multiple resistor calculations for both parallel and series circuit.It also has a calculator for finding the unknown resistance for a parallel and series circuit for a given total resistance .
It's unfortunate that you are not happy with the App. Anyway we will try to improve for better user experience

### 1/5 — Achtung, ist der gleich Quatsch wie der andere Rechner der Entwickler

*2023-04-30*

Habe zweimal für den gleichen Blödsinn abkassiert, so ein Betrug 🤬

**Developer response:** Hi
Bitte kontaktieren Sie den Support unter contact.pugal.apps@gmail.com.
Wir werden versuchen, dieses Problem zu lösen.

### 1/5 — Took my money and hasn’t unlocked!??

*2023-02-07*

I paid to unlock other calculators and it hasn’t worked. I tried to „restore purchase“ within the app and I get „unknown  error“. 

I try to email the developer within the app, and just get an error. This is ridiculous, I’ve literally paid for nothing. Please resolve this asap, I’m complaining to Apple about this

**Developer response:** Hi
Kindly contact us at contact.pugal.apps@gmail.com. from support page in the App
we will resolve this issue.

### 1/5 — App keeps trying to repeatedly charge me after I already paid for full version

*2020-08-21*

Not sure if it’s a bug but there’s no point to paying the $3.99 fee if I’m getting prompted to pay for it each time I try to use it

**Developer response:** Dear Customer,
Kindly contact us @ contact.pugal.apps@gmail.com we would try to resolve this issue.

### 1/5 — Disappointed

*2020-06-11*

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.

### 1/5 — Paid but not unlocked - no response

*2020-03-15*

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.com

### 1/5 — 收费的

*2018-05-07*

🕳，收费的

### 1/5 — Annoying

*2018-02-19*

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

## Most praised reviews (10 highest-rated)

### 5/5 — Great

*2025-11-28*

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.

**Developer response:** Happy to hear 😊

### 5/5 — Change language

*2025-08-28*

Gooooood

**Developer response:** 👍

**Developer response:** happy to hear 😎

### 5/5 — Fantastic app

*2024-08-30*

Learnt all this 40 years ago but now I can do the calculations instantly and it shows a diagram and formula .

**Developer response:** Happy to hear 😎

### 5/5 — Spannungsrechner

*2024-01-16*

sehr gut, kann schon längst Vergessenes wieder beleben :-) !

**Developer response:** 😎

### 5/5 — Best thing since sliced bread.

*2023-08-14*

Best this since sliced bread.

**Developer response:** 😎

### 5/5 — Résistance atomiseur

*2022-10-18*

Très pratique pour calculer la valeur souhaitée d’une résistance quand on utilise une box mécanique

### 5/5 — top

*2020-10-25*

muito bom

### 5/5 — Nützliches Tool für Elektropraktiker

*2019-05-01*

Eine nützliches Tool für die schnelle Berechnung vor Ort.

### 5/5 — Free basic calculations for EV owners and a whole lot more!

*2018-07-05*

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:** Dear Jim,
 We will accommodate the features, you asked for, in our next update.
