LOVE. THIS. APP!

This is a fantastic tool that is more than worth the price. I been using this scanner for a few years now and it is truly indispesible for me. This is really is a professional level tool for helping you get a quick assessment of your WLAN.

My favorite feature is the “Advanced” tab. This tab reveals the IEs (information elements) in the probe requests of clients and gives you a lot of information you normally only see if packet captures.The amount of information and detail you get form this app is amazing.

Also, the developer is very responsive to feature requests and bug reports and the app is regularly updated.

There are not many pro-level wireless tools for Mac and this is a great one.
