I have used Anki extensively in the past. It works decently for me, but the primary issue I have is that there's no streamlined way to add information I have found. e.g. if I hear read a figure I want to remember, I have to go take out my phone/laptop, open the application, format it some way into a cloze style question, then go back to what I was reading. Do you use it in a more streamlined manner?
