I deleted it. It launches on startup and I do not want it to do that. There are no preference controls for you to control whether to launch on startup. And it’s NOT listed in System Preferences > Login Items. If you don’t want it to launch on startup, you have to delete it.No application should launch on startup without giving the user a choice.If this is fixed soon, I’ll re-rate version 1.1.

I really like this ruler for its clean look. It doesn’t junk up the screen and it is semi-transparent when not active. The default option to launch on start-up is a little obnoxious, but I was able to disable this feature.

It's my bad for not noticing it only measures pixels. But now I'm trying to delete it, and it's impossible. It opens automatically on login (seriously? You can't opt out of that?). There's no way to quit the app so you can delete it--option click doesn't work, there's no menu item; it doesn't show as a force quit option. Horrible.

Not A ruler , just Pixels Dissappointing.
