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
Boost Your Scores - Master USMLE concepts with 8,000+ multiple choice questions and 15,000+ flashcards

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.

All in one tool you need for med school! But you need the subscription FYI!

Bugs recently fixed! Great study tool on the go that has all my created and class uploaded flashcards! Plus I can watch all the osmosis videos right on the app so everything I need I can access with my phone on the go. Basically everything you need to study for med school can be found on osmosis and they are super quick to respond and help with help with any questions!

Unreliable App

Ultimately, not worth the download. It is extremely buggy on the iPad with most videos not playing or audio overlapping with previous parts of the video. I pay $9.99 for the videos only and can’t use them on my iPad Pro and the subscription doesn’t cover videos on the osmosis website, so I can watch on my iPhone or not at all.

I don’t need the extra features of a full subscription but apparently that’s the only way to have reliable, multi-platform access to all of the videos. Bummer. Will be cancelling my subscription at the end of the month and relying on OME instead.

Developer Response ,

So sorry to hear this. Can you refresh your app so that you can get our recent patch and update to version 4.1? If you're still having an issue can you please contact our support team at so that we can look into your issue? Thank you!
