Kno has on offer thousands of educational books available for students on the iPad via its app Textbooks. The application allows for students to get a 3D object view in their textbooks of subjects and objects related to Chemistry for now but would be extended to cover other subjects also soon.
Then there is the Smart Links feature which focuses on videos but is in beta stages right now. This allows for YouTube or other such video content to be displayed on the textbook with no need to block out space and also any other relevant material. This will only held in building a better grasp of the subject. One can also get thousands of educational clips that includes algebra and calculus by Khan Academy and there is news that others too would be joining in.
The Kno’s app right now works only on the iPad and the cost of Textbooks ranges between 30 to 50 percent less than the paperback form of the same.
