Apple has over 650,000 apps on its App Store. That’s a lot of applications compared to Google’s 600,000 apps on Google Play and Microsoft’s 100,000 apps in its Windows Phone Marketplace. But if your favorite apps such as Instapaper and Angry Birds Space HD Free have been crashing lately, then you must know that corrupt apps are reportedly thriving in the App Store. This was first observed by Instapaper creator Marco Arment. In a blog post, Arment said that a seemingly corrupt update being distributed by the App Store in many or possibly all regions is to be blamed.

“Last night, within minutes of Apple approving the Instapaper 4.2.3 update, I was deluged by support email and Twitter messages from customers saying that it crashed immediately on launch, even with a clean install. This didn’t make sense – obviously, Apple had reviewed it, and it worked for them. My submitted archive from Xcode worked perfectly. But every time I downloaded the update from the App Store, clean or not, it crashed instantly,” the Instapaper founder wrote. Some developers are also saying that the problem might be caused by Apple’s FairPlay wrapper, a piece of software the company adds to all apps for sale. Check out the full report by Arment here.
