Overlay Lite 4+

This is the free version of our Overlay. Free is free, there are neither in-app purchases nor subscriptions. You can benefit from all features of the Overlay. Compared with the professional version, there is only ONE difference: The overlay picture you are using will be blended with a watermark of the app name and version. We hope you like the idea of the app and get your job done with ease.
A frame that allows you to have an image or even PDF displayed semi-transparently in front of everything and click through. It enables you to easily copy, trace, or compare designs, images, and documents since you can lock the frame and make it undisturbed by mouse gestures.
It’s a transparent overlay of an image or document on your screen that you can click through - like a transparent sticker on your screen.
Overlay Lite is especially useful for artists, designers, and students as it allows you to make your art or design from or reference photos and screenshots.
