Screen Ruler Professional

  • on 26 Sep 2011 with the initial release of the new Screen Ruler Professional the good old Screen Ruler Free became part of the history. The new product, althought starting with version 5 (as a sign of appreciation to the free tool) is in fact completely new product (and that's why I renamed it to "Screen Ruler Professional"). It is hard to say what is not new in this version 5.0. I rewrote the whole program from scratch -- there is no even one line of code used from the old version (the new Screen Ruler is written in different programming language). Some of the new features are: unlimited number of guides, multiple-display support, display calibration included, rotation & angles support (you can measure diagonally), you can now use different figures (rectangles, squares, circles and so on), more settings, Mac OS version... The list can continue, but you get the idea.

    The "bad" news: Screen Ruler Professional is shareware (14-day free trial available on the download page)
