Pocket Lint
Pocket Lint was a personal project to keep track of my spending using my then new iPhone. I figured it would take me a while to learn Objective-C and the relevant Cocoa Touch APIs but actually ended up doing it in about a month, just in time to submit the application to be included with the launch of the new iTunes App Store. While working on Pocket Lint I really learned to love Objective-C and Apple’s elegant API.
