This app will teach you in a different way than the apps out there. You will be shown a picture and the words, so it is easier to memorise them. But you will only be given three lessons: lesson one, fifteen, and thirty. I would like to give this five stars if what it provides are lesson one, two, and three--how can I understand lesson fifteen and lesson thirty if I didn't study the rest?
Still, this app is good enough. But for the full version you have to pay.
