"I’ve finally found the best all-in-one image annotation tool for iOS – Annotable for iPhone and iPad." —— Federico Viticci of MacStories

Features (many are free, some are unlocked with purchases):
◉ 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.
◉ Or on the contrary, highlight something with Spotlights.
◉ If you really want to focus on a particular spot use a Loupe.
◉ 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.
◉ Fully support Action Extension, Photo Editing Extension, Edits Sync via iCloud Photo Library, URL Schemes, 3D Touch, Wide Color…Annotable utilizes your powerful iOS system to the extreme.

Distinctions from many other similar Apps:
