The app is very good if you want to know the basics of german and learn it overall to an advanced level! The 12 months subscription is also very affordable (and cheap) and I can study and learn through this app by spending only 5 Ron per month which is about 1$. Other apps offer the same service, perhaps worse and expect you to pay 10$ per month. I loveeeee this app so much. I am a high school student and I really recommend it :)
