Apple today seeded iOS 8 beta 4 to developers. The update brings the usual bug fixes, a few UI tweaks and the addition of Apple's Tips app. The new stock app currently offers six tips with tutorials, but Apple promises it will be updated with more tips each week.
The Tips app includes tutorials like, how to quickly respond to a notification, how to enable the "Hey, Siri" option, and how to send a spoken message. According to iDownloadblog, there is also an option to "Like" individual tips, but it "apparently doesn't do anything". You can also share you favorite tips on social media sites like Twitter or Facebook.
