Mobile or Web Development?

I plan on starting Treehouse courses next month as well as utilizing other resources and I'm interested in web development as well as iOS development. I have a lot of free time so I will study for hours everyday and would like to know whats a better choice? Im interested in app development because I love apps and would eventually like to become a appreneur. I know if I study web development I will be able to get a job by the summer and create guaranteed income for me as well as experience.Basically what I'm asking is which path will have more opportunities for me? Thanks.. P.S. I have no background programming experience but I have dabbled in HTML and CSS.
