Markup is a hidden powerhouse in iOS and iPadOS. First introduced in iOS 10, the image-annotation tool has added more features and improved its interface. In the latest operating system releases, Markup has had its appearance redesigned and a new we-page capture option added. Using all the options may not be obvious at first glance.
If you want to add a caption to a photo (including speech bubbles), highlight a detail, point at something in an illustration, or add callouts in a screen capture, Markup provides minimal but able tools tailored for quick application and modification.
How to invoke Markup
Whenever you take a screen capture, the OS puts a tiny preview in the lower-left hand corner of the screen as an overlay on your current app for a few seconds. Tap that and you’re brought right into the Markup environment.
