snow leopard compatible version available by emailing beta@istumbler.com

Would be nice if it didn't crash all the time. This is what I get in the log:

pretty good, but... take a look at KisMAC instead.

I can think of at least 3 apps this alone replaces (namely Macstumbler, Flame, and Bonjour Browser).
Very useful to have in your Utilities folder :)

I use it all the time when setting up wireless networks. Very useful!

Solid app, and the spectrum widget is a god send, even tho I can't stand widgets.

I was using MacStumbler until I read about this last week. My new stumbler of choice!
