Screen Marker

By Lomation

Open the Mac App Store to buy and download apps.


Screen Marker allows you to write and draw directly on your desktop and above all of your opened applications. You can use it to highlight areas you want people to notice before taking a screenshot, draw on "smartboard" in classroom settings or just doodle away during those "important" meetings.

Screen Marker was designed to be simple to use but robust enough for your average doodling needs.

** Note - Screen Marker is not designed to work with individual applications like Power Point. Screen Marker is utility to draw on your desktop, not inside individual applications.

What's New in Version 1.1

* New user interface, got rid of the old ugly window.
* No more hot-keys! Simply click on the mode you want to be in using the new action icons and hold down your mouse to draw or erase.
* 7 new icons representing 7 new actions you can perform.
* You can move the controls to the right or left sides of your screen (sorry, can't save location yet - next version)

Customer Reviews

use the menu on the left

I wanted this for a class I'm teaching, where I'd like to draw arrows and circles on top of open files and even movies. Looking at the reviews, I got worried that I wouldn't be able to switch back and forth between this app and another, without quitting, or that it wouldn't work on two-screen mode. For 0.99, I figured I'd give it a try. On the two-screen issue, I just mirror displays, so no problem there. As for switching back and forth between other apps, it is no problem-- just use the menu appearing on the left side of the screen. There is an eraser there and color choice, etc. I guess an issue is that there is very little documentation, so I just had to find it for myself. I like this thing. Very well done.

Works as described

This is a not a perfect app for drawing on the screen, but reviewers who say it doesn’t work, I suggest you look for the menu bar that pops up on the side of your screen when you launch the app. The menu bar does not appear at that the top of the screen. It’s in the menu bar where you can turn on and off the marker, change colors, delete what you have drawn, etc. You can take screen shots of your drawings and annotations.

My wishlist for this app:

Annotation tools that give you perfect lines and shapes
A way to type letters on the screen
Keyboard shorts to activate features

Anyway, thanks for making this app very affordable.

Mostly good - powerpoint tip included

My main use for this was drawing on top of powerpoint and omnigraffle while presenting over WebEx. Omnigraffle works great, no problems. PowerPoint is a little different. You can’t run PP in full screen slideshow mode, but you can run it in windows slideshow (change settings under (Slide Show -> Set Up Show). It’s not perfect yet, but very close. I consider it a limitation of PP than Screen Marker. Multi monitor is cumbersome, but easily worked around by mirroring or just using one monitor while sharing.
