"I have had this app for a while now, and I always found it really useful aid for teaching.Typography and all the details and classification of type, can be a dry subject and a dry, empty ditch blocking the way to learning for many young people and students. This app, helps to bridge that gap by making the subject come alive.What I like best of all, is the way that it uses the qualities and capabilities of the device to bring the subject to life. Books look great, but often books on Typography get left on the shelves. With this app I can project to a room full of students and show them right in front of their eyes what's going on. Its live and its interactive and it's really useful. Great price too."
