A few alleged iOS 8 screenshots including icons for Healthbook, Preview, and TextEdit have been posted on a Weibo account. The shots are legitimate, according to 9to5Mac.
Healthbook’s icon is very similar to the Passbook icon, and Preview and TextEdit’s icons match the Mac versions.
Earlier today, it was reported that Apple was working on iOS versions of Preview and TextEdit.
Also, a lightbulb icon for an apparent app named Tips is included in the screenshots — it’s unknown at this point what Tips is, or what it does, but it may be some kind of iOS 8 user guide. A settings screenshot was also spotted on Weibo, noting version 8.0.
