As featured on MacWorld's This Week In Mac Apps:
"The app lets you open an image (including, of course, screenshots taken from your own Mac), and add all sorts of annotations in the form of text, graphical elements, highlights, callouts, and more. And, when you’re ready, Orion Markup’s powerful sharing features mean that sending your work to friends and colleagues is just a click (or two) away."

Orion Markup supports a complete suite of annotation objects. Featuring:

- add notes and outlines to image files and PDF documents

- photo magnification bubbles: creates magnified versions of selected image areas (fully resizable, available in circular, rectangular and various polygon shapes)

- multiple sized outline boxes and text labels. All outlines and labels supports formatting options with hundreds of fonts and colors

- lines and arrows of various patterns and thickness (solid, dashed, dotted). All lines support optional starting and ending arrows

- fully resizable black-out boxes (for hiding image zones that should be private)

- fully resizable dim boxes (for darkening areas of the images, useful for indicating unimportant or non-significant sections)

- predefined number tags (perfect for documenting instructions and steps in manuals)

Make it simple to export and share:
- exports and saves to PDF document format
- exports and saves to JPEG and PNG image formats
- share instantly through Messages, Email and Clipboard
- share between devices through Air Drop
- share through direct integration with Twitter and Facebook

Ratings and Reviews

Great App and Great Support


I couldn’t get started with Orion. The reason was that somehow the pictures I wanted to mark up had been saved as “TextEdit Documents” (whatever that is.). I hadn’t notice that, but since they weren’t .jpeg or other standard image format they wouldn’t load into ORION. I emailed ORION and they got back to me the next day and pointed out what my mistake was.

After fixing that problem I now love the program, especially the Zoom Bubble feature. Very clever. I also appreciate the fact that your work product is saved in ORION. You “export" the marked up image (which saves it as) an image (e.g., .jpeg) file. Then, if you don’t like the resulting marked-up .jpeg image you can go back and reload the ORION work space (“document”}, modify it and export it again as a .jpeg image that includes the revised mark-ups.

Was great UNTIL!!!!


Lost drawings I had been working on for a week, multiple times. Saved teh drawings, happen to leave the program running and then when I reopen the drawings they are saved with the current date with NOTHING on the pages. ALL OF MY WORK GONE!!!!!

Very frustrated right now!!!!!

Hi, I'm sorry hear this, please get in touch with us, we would like to learn more about what happened so we can help troubleshoot if it's caused by the app.

Don’t Buy This


It doesn’t annotate images. It intends to create a document containing images and annotation. I want to quickly add an arrow or callout to an image.

Maybe I could live with that but it does a terrible job of that, too. It has a zillion apparently identical tools that you are supposed to drag onto your canvas. Once there, they don’t do what you want.

This is a terrible program. I am incredibly glad I only spent a buck on it even though it’s not worth that much. Off the hard drive it will go.

Thanks for taking the time to leave your feedback. We are sorry you're having trouble with this app. After adding annotations to your images, please use the "Export" option to export the marked up image, you will have options to save your edits in PDF, JPEG as well as PNG format. Unlike simpler annotation tools that only allows you to add "one-time" annotations, Orion Markup allows you to save your notes and annotations into a native design document, this makes it easy to "edit and reuse" your annotations in the future.

If you ever decide to give this app another chance, please send us a note at, we will be happy to guide you along. :)
