Hi,
I was using Anki before discovering remNote. One function I liked on Anki on Android was, that you could scribble the answer with the pen and then click on “show answer”.
Of course it is faster to type the answer into the text field with the keyboard. But the scribble answer request would be quite useful if I had the answer wrong. Once I figured out I had the answer wrong or didn’t remember the answer at all, scribbling the answer helps me to remind it next time.
I prefer to not export the rems in Anki to use this function.
