### 1/5 — 电气工程垃圾软件

*2026-01-21*

垃圾软件不能用

**Developer response:** 很遗憾，这款应用未能达到您的预期。我们将持续努力改进应用及其功能。

### 2/5 — Undersized wires

*2025-03-24*

#5 for a 200A circuit? Guess this is not based on NEC, or common sense. I’m residential/commercial electrician and this app not helpful.

**Developer response:** kindly contact us @ contact.pugal.apps@gmail.com. we will try to resolve the issue.

### 1/5 — Idioma

*2024-07-11*

Bom dia!. O aplicativo, está faltando a funcionalidade pro usuários alterar o idioma preferido. O salvamento dos cálculos é o mesmo envio em PDF caso eu tenha feito um calculo elétrico.  Atualiza a versão de idioma por gentileza!.

**Developer response:** Adicionará o recurso para alterar o idioma na próxima versão do aplicativo

### 2/5 — Bug

*2024-04-24*

Nessa última atualização de 04/2024 os dizeres dos cálculos não aparecem. Precisam corrigir. Uso 11 pro Max v17.4.1

**Developer response:** Hi
O problema foi corrigido na versão atualizada 10.1. Lamentamos o inconveniente.

### 1/5 — Recent update destroyed app

*2024-04-23*

Recent update destroyed app, can not see titles to any calculations and it will recognize my previous unlock purchase. Please fix

**Developer response:** Hi,
The issue is fixed in the updated version 10.1. We regret the inconvenience.

### 1/5 — Annoying app

*2024-03-13*

I downloaded to test but I can’t use it every single input or option change it ask if want to buy it…. Like to input a capacitor 370mf 450v it ask you 14 times if like to buy the app, never saw something like this…..

**Developer response:** hi
You can use all unlocked calculations in the free version. But to use the locked calculations, you got to buy the App. It's an one time payment and you can use the App in both iPhones and iPads with all future updates coming for free.

### 5/5 — Parabéns

*2023-12-27*

Software otimo

**Developer response:** 🥰  Thanks

### 5/5 — Ok

*2023-02-05*

Ok

### 1/5 — Terrible

*2022-03-28*

You download this app to test it. Was not minutes into testing and see what it can do that the message pops up in your face to pay. You haven’t even finished looking at a piece of it yet.

When you make it that annoying, the app is already garbage. You want to force people to pay before they know what they are getting. That is a sign.

**Developer response:** The first 5 calculators are free to use.
And for unlocking the remaining calculators, you got to make a one time payment.
Once unlocked, the App works both in your iPhones and iPads.
