Verifying In-App Purchase Receipts with StackMob

Posted on November 19, 2012

Since it was first introduced in iOS 3.0, in-app purchase has emerged as an important tool that iOS developers can use to bolster their revenue and stay in the black. In-app purchase only helps, however, when money actually changes hands.

Sustainable Pricing in the App Store

Posted on October 22, 2012

The subject of App Store pricing has popped up on my radar a lot recently, and I'm a bit surprised since I thought that debate had been long-since settled. After all, prices quickly dropped after the launch of the iPhone App Store, and it's been downhill ever since.

How to Attend a Conference

Posted on September 28, 2012

I wrote earlier that I attended 360iDev a couple weeks ago. I also got a chance to attend SecondConf in Chicago last weekend, where I had the opportunity to speak.

The iPhone Developer Community

Posted on July 4, 2010

Being an independent iPhone developer is Learned great, but it comes with some limitations that larger software shops aren’t as constrained by.
