Here's what a few of our users had to say:

“I have the Osmosis app downloaded on all my devices and use the flashcards/questions when I can't be in front of my computer. I've been able to significantly reduce the amount of study time I put in while still maintaining great scores, particularly in Anatomy.”

“The pop-up notifications from the app are amazing as they keep me engaged with the course content, which leads to even more retention with less effort! Other study resources have been more tedious for me to work with, but with Osmosis I can actually finish studying on time!”

Osmosis is AMAZING!! I have been a fellow user since my first semester of medical school when the app was not even half of what it is today. I still liked it then because it gave me a different approach to questions and allowed me to practice the topics I was covering in lectures, all while I was grabbing a coffee, or walking over from point A to point B, and even from the comfort of my own bed while going to sleep. When Shiv and the rest of the Osmosis team launched Osmosis Prime, I really didn't think it could get better...ohh but it did! After switching over to Osmosis Prime and inputting my information and test dates as well as my STEP 1 date, the app has allowed me o practice relevant material that goes hand in hand with my schedule of lectures, exams, and more! If you don't have this app on your phone yet and haven't joined, you must give it a try. The best part of it all is that you get a free trial when you join allowing you full access to the app so that you can determine whether or not it is something you want to continue using or not. If I had to rate this app I would give it 5 stars for uniqueness, efficiency, user friendly, engagig, and FUN! Who said learning can't be easy and fun?!?!
