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.

Every language learner should get this app. The only thing I would change about it would be to allow users to choose how to organize their books (e.g. alphabetically, by author, by language, etc.). Being able to create folders or "shelves" in the library would be another option. Everything else about it is wonderful. Being able to upload your own books is great. The translation functions work really well, and I love having multiple translators in case one is having trouble with a word/phrase.

I'm currently learning Russian, and the app is great in most aspects except that when I try to play the audio for a paragraph translated into Russian, it still plays the English audio. I've changed all the settings to allow everything to be translated through Google speech services, so I'm not sure why it won't play the Russian audio. Otherwise, a great app.
