Have a ruler or grid on your screen any time, any where, with the push of hotkeys. The ruler can automatically measure objects shown on the screen - virtually any objects. Works great with other apps. This is a must-have tool for graphic design or picture editing.

- Provides pixel-level detail for measurement
- Allows for free vertical or horizontal movement of ruler on screen
- The smart ruler automatically recognizes objects which user intends to measure and provides dimensional data immediately
- A grid (adjustable) can be turned on to assist positioning in your own applications
- The ruler/grid will not interfere with other apps running at the same time. instead, “Ruler on Call” allows you to measure objects and help position them in any other apps, especially when they don’t have a built-in mechanism for object alignment or resizing guidance.

“Ruler on Call” lets you lay a grid or use a ruler over other app’s screen and even automatically measures objects for you to help you stay productive. You will definitely love its utility and ease of use.
