iPhone 5s reportedly twice as crash-prone

App performance monitoring company Crittercism says that apps are twice as likely to crash on an iPhone 5s as an iPhone 5 or 5c. The company says that the crash rate of apps running on the iPhone 5s is around two percent, compared to other iPhone 5 models, according to AllThingsD.

Crittercism CEO Andrew Levy attributes the increased rate of app crashing on the iPhone 5s to the differences in hardware. The iPhone 5s uses a 64-bit A7 processor inside; it's a configuration that app developers didn't have an opportunity to test for before the phone went into production.

Levy says that Apple is doing "a really good job" at addressing problems with the new hardware and the new operating system as they come to light.

Crittercism helps mobile app developers understand why their software crashes and enables them to make optimizations to improve user experience. Their software works on iOS, Android, Windows Phone 8 and HTML 5.
