Great addition for any graphic UI designer

A great tool, just what was looking for. One slight headache was it does not work on applications running on full screen. That would be amazing if that fix was issued, but apart from that, an essentail tool by all means. Thank you :)

Calibration is slightly off - fixable?

I've used an earlier version of this app, and it was spot-on accurate on my iMac 27" 5K screen.

This one, not so accurate. Using the mm scale, it's too short on screen by about 3mm in 300 (1% or so) and using the inch screen, about 5/16" in 12".

If there's a way to calibrate the program to the screen, I can't see it. Is it possible to edit or fix this calibration error somehow? I'd give it five stars, if fixed, but only maybe 2 otherwise.

Doesn't support angled rulers

Seems to do a good job of basic vertical and horizontal measurement. However, I was looking for a tool that could measure distances on an angle. The right hand image in the app store seems to imply that the app does this, but in fact it does not. That image is just a large version of the app icon.
