Point out what you mean! Get a picture > place a pointer > zoom in > share. Its that easy!
"PointOut is a free app for iPhone and iPad that supports multiple types of image annotations and canvas layouts. You can add pointers, borders, split the canvas in multiple sections (each zoomed on a specific image detail), and tweak colors and thickness for every element. Its a powerful image annotation app with more options and controls than the simple (but also excellent) Pinpoint. But, Im primarily interested in PointOuts diagram-like loupe, added in the latest update and which matches exactly what I need for my iOS screenshots." – macstories.net
> get a picture
You can paste image from the systems clipboard, use the most recent image (last taken photo/screenshot), take a picture, or pick the image from your Photo Library. Use 3D Touch Quick Actions, or URL Schemes, to do it even faster.
> place a pointer
Pick a Layout and choose one of the pointers. You can turn some of the pointers off, too.
> zoom in
Use the pinch gesture or touch the scale bar to quickly set the chosen image scale. You can also change other various things – canvas size, colors, filters, shapes, borders ...
> share
Post the image directly on Twitter, Facebook or Instagram, or use the Share Sheet to do other nice things with it.

"I’ve been using PointOut personally for these past few weeks and it’s not an app that I use every day, but it is something that is very useful when trying to explain anything to anyone. I open it more often that I expected to and it’s one of those things that you don’t know you’ll miss until you don’t have it anymore." – infinitediaries.net
