I have a 27" iMac running Snow Leopard. In a wide range of applications I often need to use a straight edge to compare different values on charts, even sometimes charts generated by different applications. To do this I have made do with clumsy solutions like creating a floating and transparent Sticky or using Shift + Command + 4. I've also tried a small app called Crosshairs.

None of these things do what I really want. Ideally, I'd like a full screen crosshair centered on the cursor. Another way to think about this, it would give me a full height vertical and full width horizontal line that would show up over (on top of) any and all applications, just as a cursor does. Nice to haves it would give the coordinates of the display and have toolbar or right click access to turn it on or off.

Any suggestions?

SnagIt for Mac does exactly this: a full screen crosshair with pixel coordinates, when you take a screen shot. But it's only designed for screen shots. goo.gl/D0JnL –  Wheat Williams Apr 13 '12 at 14:57

While it has many more features than this, something like xScope sounds great for this.

Some main features:

  • mirroring
  • getting on screen dimensions
  • rulers
  • guides
  • frames
  • crosshair

Great little app. WAy more than I need for what I do need of it works like a charm. Thanks. –  Jagra Apr 13 '12 at 22:01

You can make whatever custom cursors you want.

Hotkeys can turn it on/off, and if you want coordinates, you could launch Pixie (or another app) and keep it in the corner.
