Annotable

Annotable is a full-featured all-in-one image annotation tool. It contains all the expected common tools: rectangles, ovals, arrows, lines and texts, fully customizable: colors, sizes, outlines, fonts, stylishly obscure private information with Blur and Pixelation. You can even highlight text on screenshots of apps like Notes, Twitter, and Safari. It feels like magic, and can really save the day when you want to share a web page screenshot with some words highlighted but forgot to select the words when you took the screenshot.
