Some of the most useful apps on iOS take system features and turn them up to 11. For a few years, the photos app has had basic markup tools but it’s felt underwhelming and lacked pro features. Annotable for iPhone and iPad adds pro-level annotation and markup tools to highlight or hide whatever you want in an image.

The iPad has become a workhorse in the last few years. Since the introduction of the iPad Pro and Apple Pencil, the transition from pen and paper to digital note-taking is more feasible than ever. GoodNotes 4 is one of the best digital note-taking and document-annotation apps available on iOS.

Skitch used to be my go-to Mac app for annotating images. Now I just use OS X’s Preview to get basic editing done in a pinch. As a blogger, I frequently deal with screenshots and images for posts. Sometimes you need to draw an arrow or draw attention to a certain part of an image. There’s never really been a good tool to do so, until Napkin.

Created by the guys at Aged & Distilled, Napkin is a new app in the Mac App Store that aims to help you with “concise visual communication.” If you’re a creative type, then this app should be in your tool belt.
