What do you like best?
Far the best app for learning i ever used, i am an active user and i bought the premium account for life which for the price is totally great.
You can learn a lot of courses from Memrise , also you can create your own courses.
The great thing is that is very user friendly and it's very funny to use, and the idea that peoples from every part of the world put their effort on it is beautiful , it's very community centered and funny with good background images.
What do you dislike?
Sometimes i can see that the app lunch some errors and is not totally well configured , but it's a minimum price to pay!
So , nothing in particular to dislike this app is great!
