The world is changing, isn't it? The new normal is learning online in the confines of your home. This paradigm shift will have to be supported by state-of-art learning infrastructure and this app is a step in that direction. Quill - The Padhai App is a gift to the new world of learning. The e-book that we present to you in this app is our nascent beginning towards providing you with a fully enabled online learning ecosystem. The e-book in this app comes to you with a host of features to replicate the feeling of learning from a physical book. You can highlight, underline, strike out content, add comments etc.; all that you could do on your own book. Quill - The Padhai App is a product of Lazy Bone Innovations Private Limited, an e-learning company which commenced its operations in 2018.
