Rocket language is amazing. I've purchased the Chinese, Arabic, and Russian. You will not find a better language learning resource out there period. The affordable price (especially on sale days) is only the cherry on top. Rocket languages is user friendly, and there's literally SO MUCH material and lessons conveniently in the app. All it takes is clicking on the app, no repeated logging in necessary and you are ready to go. The interactive lessons are around 15 to 20 minutes long, perfect for when I'm commuting to school. If you find that there is too much English instruction in the audio lesson, there is the option to listen to only the foreign conversation , and if you can comprehend those conversations, trust me you are learning. My only complaint is there is no repeat loop option for the interactive lessons so as soon as a lesson is over I have to go back into the app and press play again. Customer service is definitely about helping you and I had a good experience with them. I highly recommend Rocket Language and encourage anyone to at the least check it out.
