### 4/5 — Great

*2024-06-23, version 4.92*

Great app ! The subscription isn’t too expensive. I use it to learn spanish. A cool feature would be to be able to be tested on the vocabulary we saved in the dictionnary ^^ . It would then be the perfect app to read and learn a foreign language.

### 3/5 — Nice app with slick interface

*2024-04-27, version 4.92*

Nice app with slick interface. The word or sentence translation in duoBooks is very neat. I’ve tried competitors like readlang and lingq and they all feel clunkier. Loses a couple of stars because other apps have more functionality (like spaced repetition learning) but the app is still in development so that may come later

### 5/5 — Excellent cross language reader

*2024-01-24*

This app has revolutionized my language study! I use it with purchased ePub files in a language I am studying. The interface is intuitive. It's also very fast to use and provides a smooth experience during long reading sessions. The developer is receptive to feedback, even filling in details to improve dark mode based on user feedback.

**Developer response:** Thank you for providing valuable feedbacks! They made our app better.

### 5/5 — Excellent app

### 4/5 — Хей

*2023-11-17*

Единственный минус это перевод по одному слову на русский. Он выдает слова с какими то дополнительными символами в середине… 
А так все хорошо

### 5/5 — EPUB

*2023-09-13*

Surprisingly EPUB reader is very good. Table of contents, switching between chapters. The only thing I wanted to add is copying text, currently you can't do it. ​

### 1/5 — С

*2026-08-13*

Я не могу понять почему на планшете он не грузит не показывает книги и вообще ничего нет а в телефоне получается

**Developer response:** Здравствуйте! Просим прощения за неудобства. По описанию трудно определить причину, но попробуйте включить автоматическую установку даты и времени на iPad (Настройки → Основные → Дата и время). Неправильное время может блокировать подключение к серверу.

### 1/5 — Очень медленно

*2026-07-12*

Все бы ничего, но почему ж так медленно грузится перевод? Выбираю предложение и жду по 20-30 секунд. В итоге я в Гугле перевод найду быстрее чем тут что-то загрузится

**Developer response:** Здравствуйте! Спасибо за отзыв. Перевод обычно загружается за 1–2 секунды, похоже на проблему в соединении на вашей стороне.

### 1/5 — Книги не загружаются.

*2026-04-03*

Книги на загружаются. Даже после переустановки.

**Developer response:** Здравствуйте!

Нам очень жаль, что вы столкнулись с такой проблемой.

Пожалуйста, напишите нам на email и уточните, какие именно книги у вас не загружаются. Мы обязательно разберёмся в ситуации и сделаем всё возможное, чтобы решить вашу проблему как можно скорее.

Спасибо за обратную связь!

### 1/5 — Terrible

*2026-03-01*

Can only select one word at at time for translation. I would describe that as idiotic design and useless for language learning. Also the interface is baffling. Awful. One of the worst apps I’ve ever seen.

**Developer response:** Thank you for the feedback! You can translate not only words, but full sentences simply by tapping on it once. You can contact us via email we will help you resolve any issues. We are also working on new designs and improved reading experience, which will be available soon in next release, thank you again for the feedback!

### 1/5 — Encore un abonnement horrible

*2025-01-31, version 5.5*

Abonnement : à fuir

### 1/5 — Poorly executed

*2025-01-03*

This app first asked me which language to use for translation, but when I tried my first sample reading it translated the Spanish to German.  When I figured out how to fix this, it then said I had no more free translations so I have no idea if I’d want this app. Additionally there seems no way to search for books in a particular language.

**Developer response:** Thank you for your feedback! We’ve improved a lot in last couple of months, please update the app to latest version and try it out again. You can now import into the app any EPUB books you want in any language and read with translation.

### 2/5 — The app has started giving translations slowly

*2025-12-19*

I really love your app and have been using it for a long time.
But since yesterday, translations have started loading very slowly, I have to wait about 10 seconds, whereas before the translation appeared instantly.
What could be the problem?

**Developer response:** Thank you for the feedback.

We had some technical issues that were the reason of performance problems. But it has been solved, you can enjoy quick translations again.

### 3/5 — Translation language

*2026-05-17, version 6.6*

Would be a 5 but it keeps switching to German as the translation language for imported epub books.

### 3/5 — :(

*2026-04-17*

Так, загрузку с конца пофиксили, и это славно. Как копировать слова в свои карточки Quizlet? Опять же, я не знаю, в чем смысл отсутствия этой элементарной вещи, но язык тут не поизучаешь (

**Developer response:** Спасибо за отзыв! Ошибка, из-за которой книга могла открываться с конца, уже исправлена. Пожалуйста, обновите приложение до последней версии.

### 3/5 — Good but needs font scaling

*2024-06-02*

As well as some font face options

**Developer response:** Thank you for your feedback, we have improved a lot lately, please check out the latest version. Font scaling is available from reading menu(long tap -> “plus” button).

Thank you for your app it’s really helpful to me)

**Developer response:** Thank you! Enjoy your reading!

### 5/5 — This app changed my life for real

*2026-06-21*

I don't know who developed this, but I just wanted to say thank you.

**Developer response:** Thank you so much for the feedback, enjoy your learning!

### 5/5 — Almost perfection!

*2026-05-13, version 6.6*

I have been waiting for an app like this for a long time. It is so easy to use, but it has such a high level of excellent content when needed.

### 5/5 — Все супер, но

*2026-05-09*

Но хотелось бы чтобы учить слова можно было только из своего словаря, а не предлагаемые.

**Developer response:** Большое спасибо за ваш отзыв! ❤️

Чтобы учить слова только из своего словаря, перейдите на вкладку «Учить слова» → «Настройки» (значок в виде шестерёнки вверху) → «Источники слов» → оставьте активной только опцию «Мой словарь».

### 5/5 — Очень классное приложение

*2026-04-16*

Я в восторге, не думал, что будет так хорошо работать. Удобный интерфейс, плюс есть перевод по слову и предложению с его разбором. Так еще и бесплатно…. Странно, почему такой рейтинг и прога не в топе, думал, будет подвох. Разрабам и всем причастным низкий поклон!

**Developer response:** Спасибо!

### 5/5 — Super

*2024-05-16, version 4.92*

Interface élégante et intuitive ! DuoBooks rend la lecture de livres en anglais incroyablement simple et agréable. J'adore !

### 5/5 — Great for languages

*2024-05-15, version 4.92*

This app has taken my reading proficiency to a whole new level. I can understand cọmplex texts in my target language much faster, and the text-to-speech option is good for improving my pronunciation

### 5/5 — Great!!!

*2024-05-15*

I want to read in French and English. That are not my native language and this app helps a lot

### 5/5 — Annoying video intro

*2024-04-21, version 4.91*

I have paid version and every time I open any book I see this annoying video intro with app title. That why 4 stars and not five, why should I see it every time?

Edit: Thanks for your feedback, 5 stars. I will wait for updates👍
