Appitic is a terrific site for finding educational apps. The site reminds me a lot of Mind Leap in that a user can search by grade level or subject. Appitic has a collection of over 1300+ apps and is designed by Apple Distinguished Educators (ADE) for finding the best tools for the classroom.
I highly highly recommend checking out Appitic by clicking here!!!
