I love this app for learning Spanish! I haven't been able to find an app that works like this one, though I will say that I'm a little disappointed because of the use of AI writing the stories as it's not always accurate to the way spanish natives speak the language. Fortunately there are alternatives to those books so other than that my experience has been great so far even without spending any money on the app!

For me, this is the language-learning app I've been looking for. You can upload or paste in your own texts, it gives you easy access to translations for both words & entire sentences and it's super quick to save vocab words, there's hands-free narration, tons of customization options, etc.

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.
