iOS 8 Screenshot Reveals New Healthbook, Preview and TextEdit Icons

Healthbook is Apple's rumored fitness app for iOS 8 and its icon revealed in the screenshot loosely matches earlier descriptions. It may connect to the iWatch and track vital health and fitness parameters such as calories burned, heart rate and potentially other statistics like hydration and blood glucose levels.

Preview and TextEdit may debut in iOS later this year as part of an expansion of Apple's iCloud service. Their icons mirror those of their OS X counterparts, which is unusual as Apple uses different icons for its OS X and iOS apps. This suggests the icons are placeholders and may change before the apps are released. Tips is an unknown app, and its role in iOS 8 is not certain.

Overall, the screenshot shows the iOS 8 design appearing essentially identical to that of iOS 7, although this may change over time as work continues on the next-generation operating system. Apple is expected to unveil iOS 8 later this year at WWDC 2014 and release it publicly sometime this fall. Besides underlying improvements to services like Maps and Siri, it also is expected to include health and fitness features that will integrate with Apple's iWatch wearable device.
