I am very disappointed with this app. I open a Japanese text, and it speaks most of the words as Chinese, even though that there is a clear context of Japanese language. Both languages use the same hieroglyphs, but I expected the app to choose the proper pronunciation for the language that I am actually learning. Right now this app has zero value for me, even though I purchased the lifetime subscription for it. It might be useful if I would be learning a different language, maybe. But I am not.

Have you chosen the right language while important? Some books have wrong language in their meta info. Check is you device has Japanese voice packages: Settings - Pronunciation - Advanced settings - Voice packages. Write on apps.kursx@gmail.com, it will help me to fix the problem

I just started using this app but so far it seems great! I love the ability to customize all the colors, and being able to translate the text by word, phrase, sentence, or paragraph is so helpful! I also love that you can hear the text read out loud to understand the pronunciation. My only suggestion for improvement is that when you save a word, you should be able to select multiple parts of speech since many words function as more than one, such as an adjective and an adverb.

Might just be one of the greatest apps I've used which allows me to expand my knowledge and read books from other countries. It lets me read and translate works by lesser known writers who aren't able to publish their books in English. This app is so useful and amazing. I might be subscribing for the paid version soon!
