great app for finding wifi channel conflicts - can’t even begin to tell you how indispensible this app has been for me. biggest benefit has been in mapping out channel conflicts among wifi routers — when a wifi connection seems slow it’s often because the router is running on the same channel as a dozen other routers nearby. this program has helped me determine available wifi channels in any given area and has helped me map out optimal wifi router location by quickly mapping out dead zones.

Buggy with Yosemite - App needs to be fixed with the current OS X. The list of available networks changes rapidly and the strength of signal is inconsistent all the time. For instance, my WiFi signal strength changes from 95% to 30% without moving my computer. Please fix this app!

Worth every penny. Please do it for iPad! - The only thing im unhappy is that i cannot have the same experience from an ipad (APIs fault). I hope the latest API and ipad pro 12” Hardware lets you do this for ipad and that you get encouraged enough to work it out. Excellent experience, excellent app, nice UI/Design. This is one of the last things I cannot do from an iPad.

Go-to for interference - This is always the first app I launch whenever I get complaints of “wifi problems,” and 99% of time time I’m able to immediately identify nearby rogue access points that are screaming over my channels. It’s also amazing for wifi planning and optimisation. I end up running this app on at least a weekly basis, sometimes more.

Great App! - What a beautifully designed application. I used WiFi Explorer to test the placement of Eero access points in my home. The annotation feature in particular is very helpful. I can label each Eero BSSID with a more descriptive name (like Bedroom, Living Room, etc.) and then wander around the house to see how the signals change. Worked great.

Very useful. - Have used WiFi Explorer to troubleshoot lots of stuff including telescope mounts! It also shows things like why connectivity at the local college is so bad. 20 transmitters, ONE channel! :) Great program. Thanks for the info.

Review by MacPW

Very solid and thorough app. - Especially the graphical interface is helpful in understanding what is going on and how other surrounding networks behave relative to your own. Pretty much encompasses everything the average and semi-professional user needs to keep an eye on his/her network. Developer is on the ball with updates and the price is right for what this application can do.
