### 5/5 — Пумпурум

*2025-03-09*

Отличная прога

### 1/5 — Нет правил !

*2024-11-29*

Нет правил , как раньше ! ((

### 3/5 — Не работает

*2024-02-19*

Не могу ни чего открыть (скачать), выбираю язык Русский, и просто круг загрузки на экране.

### 5/5 — Мобильный электрик

*2021-12-18*

Приложение абсолютно идеальное! Но всё же добавлю «ложку дёгтя в бочку мёда», так как на мой взгляд ну ооочень не хватает теста на группу по электробезопасности, тем более, что но.1.4 ПТЭЭП позволяет использовать ПЭВМ для сдачи экзамена по электробезопасности по типу персонала и квалификационной группы…  Да и «перекур» было не плохо, только лучше «перерыв», так как большая часть персонала не курит ;-) А в общем и целом ну оочень замечательное приложение! А за экзамен можно и дополнительную оплату испросить с купивших приложение, думаю да и больше чем уверен пользователи не откажутся, а даже поддержат рублем сей проект! Спасибо автору и создателю за такой отличный продукт!

### 5/5 — Рекомендую.

*2021-08-22*

Отличная программа. Есть всё что нужно, и даже больше. 😃👍🏼

### 4/5 — иконки не по фешую

*2021-08-17*

на 11 айфоне круглые иконки обрезаны, не по феншую смотрится. Оптимизируйте под ай пад

### 4/5 — Мелкий шрифт

*2019-10-12*

все хорошо но очень мелко! Нельзя ли сделать возможность изменять шрифт

### 1/5 — Разработчик мошеник

*2019-08-18*

Купил приложение произошло списание 149р
Посмотрел в настройках, платных подписок у меня нет вообще. И тем ни мении спустя какое-то время опять списание 149р
Списывает деньги без подписки. Это как?

**Developer response:** Уважаемые пользователи. Никаких подписок в приложении нет. Я не продаю приложение. Приложение продает App Store. С меня они за это берут 30%. Все претензии по оплате к ним. Я на это повлиять не могу. Спасибо.

### 1/5 — Not made in America

*2019-08-13*

Appears foreign based

### 1/5 — Цена

*2019-04-14*

Цена составляла 149 рублей. Решил купить. А дальше пошло интересное списание денег. Сначала списали 70 рублей, потом 149 рублей, затем отменили списание 70 рублей и списали ещё 349 рублей. В результате я заплатил за приложение 498 рублей вместо 149. Сделал вывод больше платные приложения приобретать не буду.
