My First iPhone App

Myself and some colleagues started going over the iPad and iPhone Application Development course. It’s a class taught over at Stanford University and available for free (as in beer) on iTunes U.

After two sessions, it was time to get my hands dirty. Today I completed my first assignment: An RPN Calculator.

Not much credit to me here, I was mostly following a tutorial (but unlike in the tutorial, I made the background gray).

Here’s a glorious screenshot:

I understand that if the App Store was an actual physical software store, all my readers would already be lined up to buy their copy. Well, the good news is that the App Store is not an actual store where you have to go get in line like a schmuck. The bad news is that this app is not going to be available for download at all. It’s really a piece of junk.

But I am already brewing (in my mind) what will become the app that will make me rich beyond anyone’s dreams. The brewing is not going well so if you have any ideas, please feel free to pitch in.

At some later date I may write a little bit about my impressions of Xcode, Objective C, Cocoa Touch and this whole iPhone app development thing.

Vonage Mobile for iPhone

Sort of a plug, but here it goes: Vonage, the VoIP phone company, released an interesting app for iPhone, iPod touch, and Android (iPad coming soon).

It works like this: you install the Vonage Mobile application on your phone and log in using your Facebook account. Once you do that, it will show all your friends that also happen to have this application installed. You can then call them and talk to them, over both 3G and WiFi. And it’s free – even if they are in a different country – because the call goes over the internet.

The app is far from perfect. For instance, it does not yet support multitasking on iOS 4. But it works, and it’s free, and it’s convenient. Hopefully they work the kinks out soon. Try it out, and if I am your Facebook friend, then I will automatically show up on your contacts list. However, be careful if you are using this on 3G and have a limited data plan.
