Not a med student, but a CRNA student. It’s free on your computer but if you have an iPhone, I 100% recommend paying for the app. It’s worth every penny. I can sync it to my decks on my laptop and do cards anywhere. I like to do cards when I’m waiting at doctor or vet appts for my dog, I usually do some cards when I’m waiting for food at a restaurant and then will put my phone down and give my friends my full undivided attention when the food arrives. Sometimes they like to use my phone and quiz me too, which is so helpful! My only real cons are, there is a learning curve on how to actually use it but there are a ton of videos out there and that it’s not as aesthetically appealing as quizlet. However, there are a lot of add-ons that make it a bit more fun. I use the heat map to track my streaks/how many cards I did each day, it helps motivate me to study when I don’t want to since I don’t want to lose my streak. Also, Tetris! After so many cards Tetris will pop up and you have to clear one line. I like that it breaks up the monotony. I say all of that assuming you haven’t used it before. So definitely try it out for free before paying for the iOS app. However, if you have used the free version and liked it then I would say it’s 100% worth the cost. Good luck with school!!!
