Sorry for the tangent, but if you don't mind can you explain more how you're using it effectively? Are you speaking using "Live" mode or typing? Is it remembering and planning lessons for you or is that on you to do?
The first thing I did was ask it to continuously adjust its difficulty level based on my replies(A1-C1), it told me I’m in the A2-B1 span. Then I formalised my training on Akkusativ and Dativ, which is basically A2 level.
I have structured the lessons like this:
Every day I wake up with a new lesson. It starts with the nominativ/dativ/akkusativ table. Now I’ve also added wechselpräpositionen including translation to Swedish. It then gives me 5 sentences for me to fill out. If I have time and energy, I continue the exercises throughout the day.
This allows me to continue the practice at my own pace and at my own time.
I only type and read. I can already pronounce quite well but this may be the next step.
