Comments on Koobook-Turn epub to audiobook for Android
★★★★★Federico Mariño Zubía· May 23, 2025
it's a really good app. Not every book works and when not focused on the app or the screen is off the reading lasts only for a minute or so. Not sure if capped for premium or a bug tho. Other than those minor details its really good and free! Ads do not feel too intrusive
★★★★☆The Bookish Dad· Apr 15, 2024
Great app... I am loving this app. I'm using it on my public domain ebooks. I think everyone should give it a try. The only drawback I have is I don't think it recognizes some grammar symbols... Example: with I'll...it says I then l saying the letter L....or toy's...it'll say toy then S.... otherwise it's a great app, and I am hopeful for updates from the creator.
★★★★★Erick Bvuma· Aug 15, 2025
Good but needs playback capabilities, I want to do other stuff while listening to my books especially if I'm coughing up a monthly subscription, as well as the occasional ad showing up
★★☆☆☆camalo171· Dec 26, 2023
It reads ok, but no headphone control. I wish you could pause/resume with the buttons on my headphones like you can do with any other audio. Or at least a mini player when your phone is locked. If you want to pause it and your screen is off, you have to unlock it, open the app and then pause it.
★☆☆☆☆Cristian· Aug 21, 2024
It would be a cool concept, but unfortunately the app closes itself when you try to open an epub file.
★★☆☆☆arnaud wanet· Oct 17, 2023
The app crashes when trying to open some epub files, can be related to file size, dunno.

Even though I subscribed but still it shows ads and keep crashing besides, As a frequent user of your application for listening to Arabic books in PDF and EPUB formats, I would like to share an important observation regarding the Arabic language. As you may know, Arabic relies heavily on diacritics (such as gamma, fatwa, kasra, shadda, etc.) to convey accurate meanings. Unfortunately, I have noticed that some applications overlook the importance of these diacritics during text-to-speech render
