Apple iOS 8 software bug affects health apps

NEW YORK (AP) — A bug in Apple's new iOS 8 software for mobile devices is prompting the company to withhold apps that use a highly touted feature for keeping track of fitness and health data.

Apple says it hopes to have HealthKit apps restored to its app store by the end of the month. The bug affects Apple's own Health app and those made by outside developers. Apple didn't provide details on what went wrong.

The iOS 8 software became available Wednesday. HealthKit is supposed to create a central repository for health and fitness data, so that apps have a better picture of your overall wellness and can even recommend trips to the doctor.

Apple's new iPhones have sensors to monitor fitness activities, and its upcoming Apple Watch will have a heart-rate monitor.
