Review by Jack Blackstone

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!

Useful, Attractive Tool, Well-Maintained! - I am a netwrk technician, and I use this software often in my work. The feature set is solid, I use the graphs to help my customers understand their networks, and the author looks after his product with regular updates and feature-adds. Customers are impressed by this software too. If you think this software might be useful to you, I say go for it.

Review by Time Squire-in-Training

• be very happy this exists - Wi-Fi is a currently popular standard set of radio data comms protocols, for short range, wireless local area network coverage. It may seem antiquated, but it’s most commonly what we’ve got to work with here. This great programme helps a lot in detection, identification, analysis, and sorting things out. As of this writing, unfortunately Wi-Fi 802.11ac is the fastest version that we can generally get away with using right now. Just remember to have patience.

Review by BitingChaos

Well, thank you. - An equivalent to this on Windows was inSSIDer. That program was free up to the end of its 3.x builds. The 4.x builds of inSSIDer cost $19.99 (like this product). Well, as of June 2017, inSSIDer now costs $149. So, please don't get rid of this program!

Awesome tool! - I am in IT and needed something to help optimize Wi-Fi channels and bands. This tool is everything I need, I am very impressed and didn’t expect to find something like this for Mac. I am very happy. Thank you
