These Android and iOS builds will crash your apps more often50
The study also reveals that apps running on iOS 8 crash 2.14% of the time. That is down from the 2.31% rate that iOS 8 users experienced about a month ago. But it is higher than the rather steady 2% crash rate that iOS 7 users have had to live with.
Apps crash for a variety of reasons, some of which have to do with software glitches and some are related to hardware issues. Sometimes the problem can be boiled down to an issue with a specific device. But in the scheme of things, we are only talking about an extra crash or three out of 1,000 times an app is loaded on a phone.
