[Review] Best WiFi Analyzers, Speed Tests, and Master Key Apps

By Bernhard Mehl

I recently searched for a free WiFi speed test scan and realized there are several different—yet similar—types of WiFi apps and tools out there. It's confusing to keep track of the differences and intricacies between them.

At Kisi, we recently had to set up a new WiFi network in the office, so I downloaded a couple of different apps to see which WiFi networks existed and how fast each one actually is.

The majority of these WiFi apps and tools fall into one of the following categories:

  • WiFi Analyzer Apps
  • Speedtest Apps
  • WiFi Master Key Apps

WiFi Analyzer Apps

These tools help you find under-utilized WiFi channels that might not be used by anyone. I have to say, there might be better analyzer apps for desktop on MacOS but I’ve chosen Network Analyzer Lite by TechNet on Apple iOS.

Doing an initial LAN scan, the app shows all devices connected to the network—including printers, MacBooks, tablets and servers.

I then found one device and tested the ping to that device, which fluctuated between 19ms and 39ms every second; however, after watching the pings for a while, more and more 200ms pings showed up sporadically. A few days prior to these tests, a few co-workers had complained that their WiFi-based softphones dropped calls for half a second—this could be one reason why that was happening.

Testing additional functionalities would have required me to download Network Analyzer Pro, which includes a network speed tester, ping statistics, WiFi LAN scan details and wake on LAN, visual trace route, Whois and DNS lookup, fast/adaptive port scanner, DLNA service browser and scan & query history. For now, I was more concerned about the real ping and general upload and download rate on the network.

If you are on Android you might find the Wifi Analyzer app helpful. This free app turns your Android phone into a WiFi network analyzer. It shows the WiFi channels around you and helps you to find a less-crowded channel for your wireless router.

Generally speaking, there are tons of premium paid apps out there for the IT professional, but for this purpose I was more concerned about simple speed insights.

Extremely annoying things happen when there’s an interference in the mix—should you ever want to calculate RF interferences, check out the RF toolbox.

WiFi Speed Test Apps

For testing the real speed of the WiFi, I went with Speed Test SpeedSmart WiFi & Mobile Network. It does exactly what it’s supposed to do: Measuring latency, download and upload rates of the WiFi network that you're currently connected to.

A cool feature of this app is the 'connection grade'—my connection received a 'B' because my average speed was 23.84 Mbps, maximum speed was 28.24 Mbps and minimum speed was 16.22 Mbps, which is fast but it's not Fiber-Optic fast.

WiFi Master Key Apps

Wifi Master Key Apps are tools for smartphone users that are useful for searching for, connecting with and managing Wifi access. The apps have databases of over 2,000,000 WiFi hotspots and passwords and show the ones that are nearby on a map. End users love these apps because they can help you save money: If you can connect to a WiFi network then you don't waste cellular data when browsing the web.

WiFi Map on iOS

WiFi Map on iOS provides passwords for free wireless internet access in public places and hotspots. This app has more than 2,400 WiFi hotspots registered in New York City alone. The app works extremely well and shows you all WiFi hotspots near you. In New York City, you can find a WiFi hotspot at basically every corner of the city. The app lists the network’s name, password and indicates if there is a free WiFi network nearby. This app can be incredibly useful for tourists because mobile data isn't required when connected.

You can purchase the pro version, for $4.99 in the app store, which includes offline maps and a tourist mode. With the pro version, you can check if there is WiFi at places that are more than 4.0 kilometers away from you. If you do not want to use mobile data, we recommend considering the pro version because the offline maps are vital when searching for a connection.

WiFi Master Key for Android

This a similar application, to WiFi map on Apple, that works the same way.

AirPort Utility by Apple

Airport Utility is a management app by Apple. It can be used to manage all AirPort base stations and it also manages your WiFi Network. It gives a graphical overview of the WiFi network, information about connected WiFi devices and you can change the network and WiFi setting through this app. This app also has a WiFi scanner, which no other app has because of Apple’s API rules.

There are additional paid options that can be bought and downloaded in the App Store.

These apps can be very helpful to optimize the conditions of your WiFi at home, at work, and also on the go. Many free options can be found in the App Store and the Google Play Store.

Phone-based systems are not just a small-business solution. CEO of Kisi, Bernhard Mehl, comments: “If you see the average of three doors connected then that might seem low but, in reality, one door relates to around 50 employees—so those are locations with about 150 people on average, including satellite offices. That’s quite significant.”

Mobile Access Control Adoption by Industry

Kisi examined which industries are investing the most in mobile access control technology. To do so, the average size of mobile access control installation projects by industry were measured. Commercial real estate topped the list with 23.5 doors running mobile access per facility. Education management came in last with 1.0 door running mobile access per facility. 

Physical Security Statistics: Mobile Access by Industry


The number of shooting incidents at K-12 schools, according to the CHDS, reached an all-time high at 97 incidents in 2018—compared to 44 in 2017. Cloud-based access control companies, like Kisi, offer a lockdown feature for active shooter situations or emergencies, making it an effective protective layer for places that are targeted, such as religious institutions, which come in near the top of the list with 4.0 doors running mobile access per facility. 

Based on industry size, it makes sense that commercial real estate tops the list, with 23.5 doors running mobile access per facility. Cloud-based access control enables these larger organizations to scale more seamlessly and allows large organizations, like telecommunications, to deploy the most manageable IT solutions available, eliminating the need to create and manage a business’s own IT infrastructure over time.

“Commercial real estate is, of course, the driver of mobile adoption since they have the largest buildings,” Mehl adds. “The key here is to show that mobile-first technologies are not a risk but an innovation that brings positive ROI and allows agencies to reposition their buildings as forward-thinking establishments.”

The scalabelilty and ease of use in onboarding an organization allows many different types of industries and businesses of different sizes to adapt a cloud-based access control system, either using keycard or mobile credentials for access. 


Mobile Access Control by State

Looking specifically at the United States, Kisi analyzed in which states companies are investing the most into upgrading to smartphone-enabled access systems. Of the currently installed base of access control readers, around 20 percent will be mobile capable by 2022, according to a recent IHS report. Cloud-based systems, like Kisi, are future-proof—allowing over-the-air updates in real time and unlimited scalability for users.


“Mobile unlock technology makes you think of the major tech hubs like New York, San Francisco or Los Angeles,” Mehl adds. “Looking at which states have the largest projects, it’s surprising and refreshing that those are not the typical ‘tech cities, and yet that’s where access control technology really makes an impact.” The fact that the largest projects are seen in states outside of the typical tech startup landscape is evidence that mobile access control is highly applicable across industry sectors.
