Rocket Languages has an AMAZING platform and is the best I've seen so far. It may not be as popular as other language programs but it is the most valuable. I love how they ease you into the language and the Voice program IS NO JOKE. I'm learning Korean, and it's such a relief that the first lessons are introductions and key phrases you basically NEED to know, instead of having to learn hangeul straight away. Also, the voice recognition program is so cool and it improves the quality of your learning so much. I have genuine fun with every lesson and I'm so thankful for the Rocket Languages Team for that.
