I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D
Philip, iOS User
The app is very simple and well designed. So far I have always found everything I was looking for :D
Lena, iOS user
I love this app ❤️ I actually use it every time I study.
