Hello. This is the first review I'm writing, only because Rocket Spanish seems like an extremely effective app for learning languages. Specifically, I am talking about Spanish, although these points probably apply to the other languages, especially its structure. It's structure is very appealing and attractive, and the way you learn through sets of audio, flash cards, quizzes, which test your overall knowledge, is very simple and concise. I highly recommend giving the free version a try, to see if it's for you, although it might not work for everyone, it's layout is intuitive and easy to navigate, and the learning system is very efficient. There is only one minor issue, and that is the audio system. Talking generally works and it can read your voice very well. But sometimes, for more complex words that require more pronunciations, it can read your voice wrongly. Overall, I think Rocket Spanish specifically is an amazing tool for learning Spanish! Keep up the work, Rock Language!
