### 5/5 — Stable for natively opening DjVu documents

*2024-11-12*

My option for many years for reading DjVu documents. Opens them natively, without having to first convert to other formats.

### 2/5 — In app features crash the app

*2024-08-22*

The app is due for a major update. Moving files or adding a server makes it crash. Still useful but I need to add files by linking to a computer, if I want them to land in the right folder.

### 5/5 — Listening

*2024-08-18*

This is very useful application I can't dispense with.  Besides text reading, I often use the listening function. It would be better if it equips with temporary stop, forward and rewind buttons for listening.

### 1/5 — Постоянный вылет на рабочий стол при просмотре “PDF”

*2024-07-18*

Честно указывайте, пожалуйста, требование к объёму ОЗУ iPad.
Что трёх Гб не хватает. Что нужно 4 Гб (8 Гб или 16 Гб). Будьте предельно честными с пользователями!

### 1/5 — Не работает

*2022-12-20*

«Невозможно отобразить страницу» после нескольких отображенных страниц. Много лет пользовался этой читалкой, но версия PRO пять лет уже не поддерживается разработчиком. Печаль, пора удалить из магазина как нарушающее права пользователей приложение.

### 1/5 — Useless app

*2022-06-06*

It doesn’t work correctly. I have to turn it off and on all the time to read one document.

### 3/5 — Crash!!

*2022-02-12*

Постоянно вылетает!!!
iOS 15

### 1/5 — Выдаёт ошибку

*2021-09-05*

На версии для iPad выдаёт ошибку страницы через 2—3 страницы. На пяти книгах перепробовал. Исправьте баг,!

### 1/5 — Программа не работает

*2021-07-21*

Когда покупал про версию она исправно загружала и читала формат divu ради которого ее и покупали. Теперь она загружает но через несколько минут пишет ошибка и вся загруженная книга исчезает. Что происходит? Разработчики вы перестали заниматься этой программой? Собираете деньги на новой?

### 2/5 — Cannot load files saved to iPad

*2021-04-16*

I tried a bunch of different mechanisms for getting files into this app. It can't seem to read which files are saved locally on the iPad, it can't see half my folders in Dropbox, it can't connect to iCloud, and it does not create an action in the share menu. Really broken app.
