Grid Mask Lite

Top-most, click-through, translucent pixel grid lines guide your graphic creation; One-pixel x-y axis mode and split dividing mode make your design more accurate; Colorful overlay works over any full-screen app making it the best tool to have your job done.

This is the free version of our Grid Mask. Free is free, there is neither in-app purchase nor subscriptions. You can benefit from all features of the Grid Mask. Compared with the professional version, there is only ONE difference: When the topmost is locked, the overlay grid line will be blended with a watermark of the app name and version. We hope you like the idea of the app and make your job done with ease.

Startup Tips:

The use of Grid Mask is very straightforward. After starting, you can drag the body of the mask window to anywhere you want and resize it. One click of the Lock button will make it fixed there, inactivated, top-most, and click-through. You may consider it as a translucent coordinate sticker you put on your screen glass.

All configurations are there when you open the setting panel and all changes you made will be affected instantly on the grid overlay. Please be sure the width of the grid line is always ONE pixel, the one pixel will be calculated as 'included' in both modes.

Yes, we know you are always in full-screen mode, drawing, and gaming. :) This grid overlay can force itself to show in front of everything.

Finally, you may quit the app anytime and pick it up later just where you are.

BTW, if you need an outline of a picture to be in front of other apps instead of the grid lines, please consider our app named 'Overlay'.

Thank you for using Grid Mask and other apps from dragonBTV!
