I finally decided to take a plunge in trying to learn iOS App development. I started with creating an account with Apple Developer Program which enabled my access to download XCode / Interface Builder and Apple iOS SDK.
To jumpstart my learning curve, I downloaded the Stanford iOS App Development course from iTunes and watched first couple of lectures. That was enough for giving me basic understanding of the Tools and things required to build my first App.
The course in its first two lectures demonstrated and taught to build a simple Calculator App. I duly followed the instructions and Voila ! within couple of hours I had my first Calculator App up and running on a iOS simulator.
Taking cues from the Calculator App, I decided to build my own app for calculating the weight watchers points for my wife. 
I found out the formula they use from their WiKi entry and started coding to get it realized.
Spent 3-4 hours on trying to find out various API’s and their uses . However the result @ the end of these 4 hours was extremely heartening. I successfully wrote my first app right from the scratch. (though the idea was not original).
Now I have to think of an original idea to further enhance my App Development skills and possible write an App for the App Store.
