I love games and I’m a huge math nerd, so I made a new iPhone game based on a famous math problem called The Seven Bridges of Königsberg. I’m selling it in the App Store, but I also want to share it with everyone, so I made it open source.
This article is the first in a series that will walk through iOS programming using this game as an example. This first article gives you an overview... Read More
Testers are often thought of as people who find bugs, but have you ever considered how testers actually approach testing? Do you ever wonder what testers actually do, and how they can add value to a typical technology project? I’d like to take you through the thought process of testers and discuss the types of things they consider when testing a mobile app.
The intention here is to... Read More

The iPhone 4 features a vastly superior display resolution (614400 pixels) over previous iPhone models, containing quadruple the 153600-pixel display of the iPhone 3GS. The screen is the same physical size, so those extra dots are used for additional detail — twice the detail horizontally, and twice vertically. For developers only using Apple’s user interface elements, most of the work is... Read More
Some time ago I started a mobile app design review section on our company's website. The idea behind this "Crit Board" was simple: if mobile developers want to create apps that people want to buy, they'll need help with design and usability. But most of the time they can't afford it. On our Crit Board, developers can send us their mobile apps (iPhone apps, Android apps, Blackberry apps) along... Read More
According to AdMob, the iPhone operating system makes up 50% of the worldwide smartphone market, with the next-highest OS being Android at 24%. Sales projections for the Apple iPad run anywhere from one to four million units in the first year. Like it or not, the iPhone OS, and Safari in particular, have become a force to be reckoned with for Web developers. If you haven't already, it's time... Read More
The iPhone will always be part of a much bigger picture. How well you address human and environmental factors will greatly determine the success of your product.
