It seems like it can tick many of the boxes for effective long term learning if used properly (including not just surface learning but also deep conceptual understanding). However, my impression is that there is a learning curve and a cost associated to using it consistently, which leads to it not being used as much. Idk. What’s your experience?
I use it, but not consistently. That's mostly my fault, though. The app is really easy to use, generally, and you can really get into the weeds of settings if you want.
Mostly, though, I just use the defaults and that's good enough for my needs.
