The app might be not bad at all. However two things really make it a disaster: - There is no option to try it even for a single day - It doesn’t have a dark scheme and UI is really awful. So I just waisted 25 Euro and uninstalled it within 10 minutes. Because I barely could read anything from the screen. Update: the learning platform itself is really very good! I managed to proceed with the browser version. However the app might be definitely improved.
