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.

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.
A true blessing!!!

I try to recommend Osmosis to all of my pharmacy school friends but people get scared by the price.. trust me - ITS WORTH IT! So much, that many professors include links to osmosis videos in lecture. There is this beautiful workspace feature where you can upload your notes and make an outline and flashcard from the powerpoints. When you do the flashcards, it shows the slide associated with it so you dont have to scroll through notes to find clarification! The only downside to the app is not having full functionality like the website. I wish I could use the workspace feature more in the app, but no big deal to get online! Strongly recommend. 2 years going strong with osmosis and it never lets me down :)
Developer Response
Thank you for continuously studying with Osmosis! Wow 2 years! Kudos to your dedication to your studies as well!
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
Bug fixes, performance enhancements.
