I really like it, however the mobile app is a bit underdeveloped and hard to navigate, I cannot find high-yielded notes there, and the videos does not count as "watched" when in fact it was. I also think that the medical questions are a bit too difficult, after phisology class it is nearly impossible to answer the question correctly. Some videos also lack English subtitles which is a shame. Finally it is a bit too expensive, especially if You have to pay for at least 6-months, however I appreciate that there is free trial option. Despite all my previous points I still love using Osmosis and would recommend it to my friends. I think a good idea is to translate it to other languages, as for example in Poland there is not a single competitior (that I am aware of) on the market but there is still the demand.
