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.

More Comprehensive, Yet Easier to Use Than Wireless Diagnostics

I had been using Apple's Wireless Diagnostics program on my laptop and was looking for more information to solve a WIFI drop problem. I already knew that there are a lot of users in my neighborhood on the 2.4GHz frequency clogging up channels 1-11. But even though I am on my own channel on the 5GHz frequency, I am still losing connection. Although I still haven't figured out what's causing the dropouts, this app gave me the assurance that I am on the right track. It is so easy to use that instantly I was able to see graphically that I had the strongest signal in the neighborhood. I like the way each WIFI network is color coded. And the ability to view or not view users allows you to compare individual networks or see all of them on the same frequency. The columns can be sorted ascending or descending, so sorting the Last Seen column will cluster the network traffic by time. The Signal Rank tab ranks the networks from strongest to weakest. If you want to graphically see how the individual networks are clustered on each of the channels, the 2.4GHz and 5GHz tabs can show you just how busy your neighborhood really is (or isn't if you are lucky). The developer also has a PDF user manual on their website. Highly recommend!

Glad I bought this back when it was $0.99

It was a little rough back then, and had some crashing issues on 10.6 and 10.7, but MANY updates have come out since then and each one offers great improvements. I have had no crashes whatsoever in the last few version updates (Running OSX 10.7.3). Love the new color scheme and charts that were added, also the dedicated "Join" button for each network found works like a charm.

I'm frequently on a college campus plagued by over-use of certain access points, while others are left open and clear (they have been running a really out of date version of Aruba OS for the WiFi system for some time now). This gives me the ability to easily select another access point when the one I'm closest to gets too crowded.

$0.99 was a killer deal for this, but $3.99 still not bad for a great WiFi scanner which is obviously under constant development and improvement.

Fantastic for Network Admins

I monitor and manage wireless networks for my company where we provide wifi for student housing. This app is Priceless! We use Windows laptops in the company with inSSIDer but the majority of the time I will use my macbook. The only things that i like about inSSIDer over this app is the fact that inSSIDer can show 2.4 and 5ghz bands at the same time while also showing RSSI over time. It would be EXTREMELY useful if this app had the optiont to show 3 of the 5 graphs at the same time side by side. The viewing size would be small for each but when I need to take screenshots for troubleshooting i want to have several graphs showing. Also it would be great if the app had the option to forget SSID’s after a period of time. There are many time intervals that I would use; 10sec 30sec 1min 30min 1hr 1day.
All in all I really do like this app
