If you use the mobile app, you can unlock the courses by making a one time payment. Once purchased, you will have access to 24 exercises and 3 courses.
This course package for the app is different from the web based premium membership, which contains 48 exercises and 6 courses. Additionally, you can deepen your training with our analysis system of your strengths and weaknesses. Also, you have access to additional language exercises.
So, if you want to train with our web application, you can use a free membership in the first place. We have 8 free exercises that you can train with and synchronize your results with the app.
