Apple has updated its Health app in iOS 8 beta 3. The app now uses the M7 chip — currently only found in the iPhone 5s — to track steps, as pointed out by 9to5Mac. A full week of data is added to the app instantly from the M7, similarly to the step tracking app Breeze; users of non-M7 devices can manually input step data. Health can also now track caffeine intake, as caffeine has been added to the app’s nutritional categories, currently requiring manual entry of caffeine in milligrams. A number of already available App Store apps can track caffeine intake.
