While the Notes app looks the same in iOS 8, it has gained a couple of new features in iOS 8, bringing its features on par with its Mac counterpart. With the iOS 8 Notes app, you can now add bold, italic or underlined text, and also attach photos (including GIFs!) to notes.
iOS 7 was a huge change from iOS 6, in which Apple embraced parallax, motion effects, and other kinds of animations to convey depth. These changes however made some people sick, causing headaches and nausea.
