Good for the basics, but not if you progress. Sentences are longer and every small typo you make, will make you start over again. Terribly frustrating, especially if you know the grammar perfectly well. There are too many lessons per crown now, making learning very tedious, and it's nearly impossible to jump ahead by skipping levels because of this. Paid for a year subscription, to be able to continue my lessons offline. It turned out to be a scam, you can only do 2 or 3 then you must reconnect.
