Udacity helps you study anywhere with new iOS apps

Udacity is taking its free online courses to your mobile iOS devices with its new iPhone and iPad apps. It gives you access to all the courses you've subscribed to as well as whatever topic you'd want to study in the future. You can sign up for new courses and get more information on the requirements of each class and whether you will receive a certification after finishing the course. You can view the lectures on your device as well and save them for offline viewing. The Udacity app is available for free download here.
