Product Description

Finding the best WiFi signal is often a challenge. Enter WiFi Analyzer, a helpful Android app that provides clear graphical views of the WiFi signals in your vicinity. WiFi Analyzer lets you choose the strongest wireless signal that has the least amount of traffic and interference.

Five signal-strength screen views:
Channel graph

Based on signal strength, the channel graph shows an overlay graph of each wireless network around you. A different color is used for each network.

App Name
Channel rating view
Time graph

The time graph tracks real-time signal strengths. While the colors may look jumbled at first, they become clearer as the graph fills up. Tapping a specific network box at the top of the screen brings that network to the front of the graph.

Channel rating

The channel rating indicates the signal strength of all available channels. You can also select a channel for your own WiFi network.

AP list

The access point lists WiFi access points around you and indicates which network is being used for each, as well as on which channel a network is found and if its secure or not.

Signal meter

The signal meter shows the signal strength of a single access point. The Menu button allows you to choose different access points for the view.


Swiping your finger across the screen switches between the views, which can also be accessed through your phone's Menu button.

WiFi Analyzer lets you take a screen shot of any signal strength screen. And WiFi Analyzer's many setting choices allow for automatic network scanning, selecting the scan interval, selecting screen colors, and the ability to hide advertising, among others.

5.0 out of 5 stars This APP is a powerful WIFI tool that works great! November 20, 2011
Verified Purchase
I have seen multiple comments on posts in Amazon regarding the strength of people's WIFI system. I have found this great APP named WIFI Analyzer that is free and it is a great tool. It offers multiple screens that can provide an analysis of your WIFI strength as well as all the WIFI systems around your house. It provides sound engineering data on how well your network is performing. It will even tell you which channels are the most open and best for you to choose as well as the signal strength of your network and all others:

Screen 1 is a WIFI spectrum analyzer map showing all the area networks (including yours) and what bands they are using and the signal strength. My WIFI booms at -45 to -55 DB ( a very good signal strength) all over my house and yard and it allows very fast and good access.

Screen 2 gives you an analog meter that will provide you with accurate strength readings of your WIFI.

Screen 3 provides a bar graph of your network and all of the surrounding networks and their signal strength.

Screen 4 tells you which channel you are on and which channels in your area provide the best open reception so you can reprogram your wireless router and improve your WIFI performance.

Screen 5 provides signal strength versus time recording so you can monitor your WIFI to make sure it is stable and if any neighbor is walking on your WIFI.

This APP is a great tool and allows you to walk around your home and monitor your signal strength and look for dead zones and problem areas where other WIFI systems may be causing you trouble. It can even help you aim and align your WIFI antenna for optimum performance. I would strongly suggest you try this APP. You can stop the guess work and use this APP on your Kindle Fire to check out your WIFI with a real measuring tool.

5.0 out of 5 stars Love it! Found network conflicts instantly!! March 22, 2011
I live in a populated area when it comes to wifi networks, seems like everyone around me has one. The issue was however I never took the time to look at channel conflicts. Well firing this app up immediately shows you what channel networks around you are on in a great graphical way, shows signal strength, etc. It's a great, free tool! I changed my network to the channel with the least usage and my network say some improvement. I would imagine having 5 networks all on the same channel around me wasn't helping. Great little app.

5.0 out of 5 stars An indispensable tool for a wifi tablet November 28, 2011
Verified Purchase
Wifi Analyzer is the best app of this type that I've seen. The first time I ran it on my Kindle Fire, it "saw" more wifi networks around my house than my laptop PC sees, which is probably a testament to both the app and the Kindle Fire's wifi receiver. I made a test drive down a nearby street that has many hotels, restaurants, and other businesses that have wireless networks, and Wifi Analyzer picked up dozens of signals.

The five different views that you can select from are all useful to some degree, but my favorite views are "AP list" and "Channel rating." AP list shows all the wireless networks around me and their relative signal strengths, and Channel rating shows the different channels of the network that I'm connected to. I learned that there are stronger channels than the default channel that I was using.

It doesn't take a tech geek to figure it out. The graphical interfaces are easy to read and understand.

I plan to take my Kindle Fire with me when I travel, and Wifi Analyzer will be extremely helpful in finding and connecting to a strong, stable wifi network. I think this is a "must have" app if your Kindle Fire (or other wifi tablet) leaves your home.

5.0 out of 5 stars Hugely helpful, great Fire app November 26, 2011
Verified Purchase
This app has been invaluable in improving the performance of my WiFi network. Very easy to use to determine signal strength (helped me position my router for the best signal throughout the house) and it analyzes channel signal strength so you can pick the best channel for your environment.

Using it on a Kindle Fire. Works great - highly recommend!

In our L shaped house, the base station is in an office on one arm and the family room where we use the wireless, is in the other. The signal, having to pass through the kitchen, a nest of wifi defeating appliances and metal, was always erratic and the IT admin, me, regularly endured demeaning asides as others tried to do their online work. Enter the analyzer which I found surfing Kindle apps. With ease, I determined that the family room signal was never strong enough to maintain a link, so I purchased an extender for the network. Again with ease, I found the optimal plug to install the extender. The family room has become a happier place for me since removing just this one categorical source of derision. Save your marriage, save your family, defeat a weak link, this analyzer beats a therapist.

Useful for finding a wifi sweetspot, but now has embedded ads in the amazon appstore update.. Sorely dissapointed in this downgrade to an excellent app. Would rather have an option to purchase/donate to get rid of the ads.. though recently the developer has added a snooze to the ads which has made it much more usable..and has improved the general feel for the app
