There is no functionality to allow you to quickly click on a word that you don't know to figure out what it means. Instead you have to wait through the painstakingly slow audio to hear someone tell you what it means. Very frustrating, especially if you're like me and learn better through seeing.

Response from Rocket Languages: Hi Michael - I am not sure what you mean here as every word/phrase in Rocket Chinese has the Hanzi, Pinyin, English translation and the literal translation. We have also recently added subtitles to the Interactive Audio course tracks to make following them much easier!
