Using WiFi Scanner you’ll see nearby wireless access points and their details, including channels, signal levels (RSSI), noise, channel width, and MAC address, signal quality, maximum data rate, encryption, and much more. Also includes upload and download speed testing to quickly measure and analyze WiFi Internet performance problems.
“…your wireless router is fighting for spectrum with its neighbors, potentially slowing you down and making your Internet experience less pleasurable. ...WiFi Scanner helps you solve this problem by showing you all the access point(s) nearby, and suggesting the best configuration settings to get the most out of your router.” -- MacWorld
Simple, fast wireless network discovery of 802.11 a/b/g/n/ac access points. WiFi Scanner is great for determining the best position for an access point at home or in the office. After selecting the best position, the optimal channel to use can be determined by selecting the least used channel resulting in improved WiFi speeds.

so far so good
I am fortunate to have found this while on sale for $.99 - I would not have tried it for $20.
It is hard to find a WiFi Stumbler for the Mac it seems. iStumbler is old and doesn't refresh properly, KisMac crashes fairly often on 10.6.8. I'm trialing AirRadar now since they offer a non-App Store 15 day trial. Also testing NetSpot which is more of a mapping tool. Request to developers - WiFi Scanner seems to want exclusive access to Airport - please if possible allow other stumbling software to run at the same time. Right now if another app is accessing Airport WiFi Scanner's data disappears and doesn't come back until it has a chance to access Airport exclusively.
Also, there is something wrong with the Monitor feature of double clicking an entry to see more data and a time graph of signal strength. When you double click on an access point, it switches to your currently connected AP instead of the one you are trying to monitor.
So lots of potential, and since it is new it should get better. The developers seems to be WiFi experts based on their Enterprise software offerings on their website, so I look forward to future updates.
Stopped working, But there is a FIX!
I guess it stopped working when i upgraded to High Sierra or catalina not sure when.. But bascially i was only able to see 1 wifi network in the scan which was odd. This app always worked beautifully before. Turns out, all you had to do was enable Location Services, unders system preferences > security > Privacy..
back to 5 stars
Extremely useful for diagnosing Wifi issues
This app does a great job of showing all the APs near you, along with a great deal of information about each one. It graphs out signals on both 2.4 GHz and 5 GHz bands.
The interface can start off pretty cluttered with tons of SSIDs, but a little tweaking will eliminate the clutter and help you see exactly what is on each channel.
A great inSSIDer alternative.
With Family Sharing set up, up to six family members can use this app.
