    Software Reviews and Critisims

      A basic but essential tool

      Despite the sophistication of modern graphics/photo editor apps, there are times when it's immensely helpful to float a ruler above other open windows to get a simple measurement in pixels of on-screen objects. I have been a happy user of earlier versions of Free Ruler since around 2002 or 2003 — but although it still worked in PC Mojave, it hadn't been updated since 2007. What a delight it was to discover that the developer rewrote the app in 2019 for compatibility with PC Catalina (and, presumably, future releases). Thank you, Pascal!

      Satisified user for many years

      I've been using Free Ruler for longer than I can remember, probably several decades now. It is a must-have for anyone involved with anything related to design, from desktop publishing to web and software development. Thank you Pascal for contuing to keep this software up-to-date and free all these years. I just sent a token of my appreciation via PayPal (I'm not partiularily wealthy so it's not much but long overdue... hopefully someday I can send more!). Cheers.

      Still works!

      Sometimes you just need one tool that does one thing, and does it well. I use this ruler often. It's been a little while since the last update, but there seems to be no need to update, since it still works perfectly. Good stuff.

      Super useful!!!!

      I user this app for all kinds of things, from lining up elements when video editing, to working on still graphics, and most recently to checking architects drawings of a home remodel. It is incredibly useful and I would gladly pay for it if it weren't free.

      A Classic Comes Back

      Free Ruler is one of those small utility applications that really provides a lot of value and is useful in so many ways even beyond graphic and web design. The developer Pascal is super quick to respond to questions and support requests. Get this!
