I can read French and chose Rocket French because I needed to learn how to pronounce the language correctly and acquire conversational skills for an upcoming visit to France. The course meets these needs and is well structured; words and grammar from early lessons come back in later ones to reinforce what I've learned (or forgotten). The phone app is especially valuable because it uses speech recognition to grade my pronunciation and catch my errors; I wish the browser version did this as well.

The user interface makes it easy for me to report problems and the staff is very responsive in either referring them to the development team or clarifying things I misunderstood.
