Ratings and reviews

So far this app is pretty good. You can practice spacing reading and writing, and the spaces repetition is quite good at predicting when you are about to forget a word or sentence. It can be a bit annoying when you are trying to speak, and it cuts you off with the answer though. I would appreciate a little more time to answer, especially for the longer phrases. The ai voices can also be hit or miss depending on the language. Korean sounds okay for the most part, but Thai tones aren't fantastic.

I wish you would spend less time with annoying floating elephants and fix your atrocious pronunciations.

Get this app if you want to use spaced repetition software for language learning without having to spend a lot of time creating your flashcards. Anki is great, it's highly customizable but for me that's also its problem. I found myself spending too much time trying to learn how to use the software and I was overwhelmed by the process of adding new cards, pictures and audio. DuoCards simplifies this so I can actually get to work learning my cards
