Ever wish you could learn by Osmosis? Now you can! Osmosis is a new app for medical students, designed by medical students, that sends you practice questions and resources so you can learn more and forget less. Osmosis uses proven learning science techniques like spaced repetition and testing effects to help you break out of the cram-and-forget learning cycles that are all-too-common in medical school. Whether you’re studying anatomy, physiology, pathology, pharmacology, or looking to sharpen your clinical reasoning skills, the Osmosis app has you covered. It's designed to take all that knowledge and literally diffuse it into your brain.

With Osmosis, you can:

Save Valuable Time - Organize all your resources in Osmosis and stay on track for your classes and the Boards with our USMLE Step 1 Study Schedule

Enjoy Exclusive Osmosis Prime Content - Access 1,000+ members-only Osmosis videos and quickly grasp the most difficult topics

Maximize Productivity Anywhere - Power through bite-sized quizzes and review your study materials from your phone with the Osmosis mobile app

Crowdsource Your Learning - Collaborate with friends in a shared workspace with custom notes, flashcards & questions

Osmosis has been covered in Forbes, Fast Company, TEDMED, Medscape, The Healthcare Blog and more, and has won awards from the Institute for Excellence in Education, PhD Innovation Initiative, and DreamIt Ventures.

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

"I explored a lot of other resources before ultimately deciding on Osmosis. I like that it is simple, easy to use, and very relevant to medical students. I also live by Picmonic, so the fact that they are integrated is even better! I used Osmosis to study for USMLE Step 1, and I'm glad I did because I ended up with a 258! I used it everyday for the customized schedule, which helped keep me on track and spend less time creating a study plan so that I could dedicate more time to learning. I like that the flashcards that I create in Osmosis appear right next to the slide that I got the information off of because it helps me to see the bigger picture, and lets me quickly review the material associated with the ones that I get wrong.”

“Osmosis is a powerful tool used to improve how students approach learning by developing more sophisticated and lasting understanding of the material. It is awesome that Osmosis follows popular and new neuroscience ideas on learning and improving how you study. I think Osmosis is an immediately relevant thing that most medical students would enjoy learning more about.”

My favorite

I'm a medical student from KSA, and I really benefited from this app. I've only started using it towards the end of last semester, so this is not my final review. Osmosis became my favorite place to start studying and get the general idea before going to my school notes and books for the details. Also a very positive thing is that the developers actually put time and effort to read feedbacks from users and use them to make the app better. Which leads me to my biggest concern, I don't think the app is getting the credit it deserves. Will that affect the effort and care put into this? Cuz a thing like this needs update, follow up, and improvement due to the fact that this is a medical based app and the knowledge never ends. I hope they keep it up and continue improving.

If you are not learning on the go via the Osmosis app then you’re not doing it right! Not only is Osmosis an amazing learning platform, the mobile app has changed the way that I study on the go. I listen to videos while I stand In the line at the store, I flip through flash cards while I wait for class to begin, I can view the new and updated study schedule and get some tasks out of the way while I wait for my friend to get ready before we go out. All of this without opening up a computer.
It’s honestly the way to go in this era of technology!

Does exactly what you need!

Their videos are a great complement to Pathoma. The Osmosis illustrations provide better in-depth understanding (I love when they zoom in to elaborate on something and then zoom back out) and include occasional histology, they usually hit a few additional topics than pathoma. I appreciate having quiz questions right afterwards. I will then watch pathoma after this to get another perspective and usually a bit more histology info.

Great app, excellent illustrations, and one of the few that lets iPhone users speed up videos.

Prime was worth the money!
