Chances without any "normal" ECs. Stanford

Hi there,

I don’t participate in many ECs at my school. In fact, the only EC I participate in is track, and I’m a state-level athlete (make state championships every year in my events). Other than that, I make apps for the app store, several of which have made the top charts under Games, and Health & Fitness, one of which was featured internationally on iOS. Together the apps have ~ 50K downloads. Other than that, I have a couple state and national level disticnctions in Physics and Math, but not too many.

What do you think my chances would be? and how can I improve my application?

GPA: 4.0
SAT: 1580 (780/800)
