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.

It's designed to take all that knowledge and literally diffuse it into your brain.

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.”

Has great potential, but missing some features/ needs to work out some kinks

I love the videos themselves. They are super helpful as a tool! However, as an app the navigating of the videos is not very streamlined, and it’s difficult to play one video after another within a subject manner. Also, if I want to project them onto my tv at home so I, not straining my neck as much it doesn’t work very well with AirPlay. After the first video plays the second one I always have to close the app and open again for it to play or screen mirror. ,I reorient is not ok when I want to multi task. I’d recommend them perhaps even making an app adapted for Apple TV.. like osmosis TV

Perfect Board Review

I was hesitant to start with Osmosis until after I studied and struggled with the content in medical school. Now, I really wish I would have used this along with the content to understand it clearly. With every video, I finally get what my med school content was saying. It’s finally making sense. The videos are short, funny, colorful, thorough, easy to understand, and are graphic with things drawn out in animations, pictures, and drawings. It reminds me of the Khan Academy that I used for the MCAT. But Osmosis is the best times a million. It’s not boring like so many programs. There are accompanying flash cards with a built in program that repeats them based on how much you know them. They get faster and faster. There are also board style questions from each section. This is my main tool to study for boards.

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.
