Improvements
I bought it because i'm studying the dogs anatomy and I think its really useful BUT you're asking for a lot of money and its not worth it. Its slow, The translation for spanish its not all good and it doesnt have the definitions of every structure (bones muscles etc) if you improve that it would be an awesome app, very good. But right now i'm not going to spread the word with my classmates about this app. Sorry, I really hope you fix it because 20 dollars its a lot of money for an app.
