Learn App Design, Development and Marketing for iPhone and iPad is a Mac program designed for people who are new with iOS software developing. The utility features several video tutorials which are presented by Kalpit Jain, the CEO of WAG Mobile company.
The application is very intuitive, plays quality video tutorials, and lets you watch the clips in fullscreen mode if necessary.
To be honest, I'm not sure how this program could possibly help you when developing apps for iPads and iPhones. All offered information can easily be found with a simple Google search in your default browser. For instance, in the first video tutorial, it teaches you which types of colors to use in your app designs (provide good contrast between visual components), how many fonts to utilize, etc.
Another thing that raises suspicion is the certificate you get once you complete quizzes. In my first test, I answered correctly to only 5 questions from 10 and still got a certificate of achievement.
Cutting a long story short, I don't think it's worth installing this program on your Mac, especially since it's not completely free and doesn't offer you much information. You can find all the details you need online.
