Hello! A kind person has already contributed to this but I want to add that this is good for learning to form sentences and memorizing/revising vocabulary. It will not lead you to fluency. It's also a great way to kick off on a language that you may want to start. Goodluck!
It's good for trying out a language to see how you like it before deciding to seriously study it. If you've already decided that you want to become really fluent in a language, it won't do that on its own but it's certainly a useful supplement.
