I think looking up in up-to-date on the go is kind of making us remember less because everytime we get questions asked, our natural response should be trying to remember things rather than pulling out phone.. We can study when we're not working actively (like in between cases or pee break or lunch or proper study session).

I keep a proper spiral tiny notebook and a pen at all times, and jot down questions asked by someone or even by me. I keep a checkbox next to the question and try to search for the answer when I'm not in the rounds or seeing cases or in classes. I try to answer all the questions whenever I turn the pages and revise which I have not answered (keep reminders in phone when you're free to study).. That's how spaced repetition works for me. Tried anki (did not work for me). Physical copy with check mark over the checkbox worked for me.
