### 3/5 — Good information | IPad Bug

*2026-03-23, version 2.0.3*

Good information but comparability with IPAD isn’t great. Headings of information don’t align with the page when scrolling and often don’t appear at all.

### 4/5 — Velmi užitečná aplikace

*2025-09-22, version 2.0.3*

Používám už roky, ale chybí mi zde jedna věc. Výpočet rozběhového kondenzátoru.

### 1/5 — Update

*2025-08-09, version 2.0.3*

Zero update/upgrade

### 5/5 — Ottimo

*2025-03-06, version 2.0.3*

Ottima app

### 5/5 — Sehr Nützlich und Übersichtlich

*2024-09-23*

Einfach perfekt dargestellt pinbelegung hab noch nie besser Geld investiert ein eine Gute App.

### 5/5 — Pour tous les amateurs ou plus !

*2024-05-17*

Amateur en électronique, cette application est une caverne aux trésors pour gagner du temps et faire quelques rappels 😁
Calculs de résistance et brochage des ports standard sont mes outils plébiscités

### 3/5 — Need update app

*2023-12-27, version 2.0.3*

App Store version 2.0 old. play store version 5.2

### 3/5 — Делитель напряжения

*2023-10-06, version 2.0.3*

Купил премиум, так как нет демо верисии для Iphone. 
Очень разочарован функционалом расчета делителя напряжения:( Невозможно рассчитать Vin при извесных R1,R1,Vout. Программа засуживает твердую тройку. Сплошное разочарование

### 5/5 — Добавить

*2023-06-14*

Добавьте цоколевки оптических патч кордов

### 5/5 — Отлично!

*2023-03-06*

Спасибо коллективу разработки этой программы. Пользуюсь со времён андройда. Незаменимая вещь, куча полезных утилит. Одного не хватает это конвертор систем счисления.
