No, we’ve made My School Books extremely lightweight for two reasons:

  1. We wanted it to use as little data as possible so you can use it on the go, every day and it won’t waste your mobile data plan
  2. We wanted it to be as fast as possible so that it still works great on low-powered devices

My School Books’ web interface is also mobile friendly, so it automatically adjusts based on your device size. The page layouts will change if you’re using a phone or tablet device, but everything is still organized the same so you don’t need to learn a new interface.
