When looking to see if wifi channel contention is the cause of an issue on my home network, I'll always turn to Wifi Analyzer on Android. What apps do you use? Are there any solutions that work on iOS?

    Until they moved to a sub model i used to primarily use InSSIDer Office.. since i do have the 2.4 fob....
    I like metageeks stuff but they have kinda priced prosumers out of the market at this point.. the sub isnt too bad, its the device that kinda costs a bit high for extended home use...(they aren't the only product thats done this.. its partly why i moved to fingbox after initially not being interested since it did too little for my liking).  Still have a need to monitor "Aunt Tilleys" network for parents who are not technically astute.. (Do wish there was more of a way to support roaming/profiles between the two .. so devices dont duplicate when they move from one fingbox to another and i dont need multiple accounts for users)  
    For android I like WifiAnalyzer(open source) .. And WifiMan  (Android not IOS) as someone else recommended.. problem is id like something inexpensive to see the interference on other devices which so far its only supported by a dedicated fob... would be cool if someone figured out a way to use an RTL-SDR to let you do some spectral analysis of the 2.4 / 5Gz band and see it overlaid at a much lower pricepoint... (Bluetooth / Wifi / cordless phones / microwaves/ ISS devices also can futz with your Wifi... esp in a crowded condo//apartment... Dont think that folks realize living in a crowded building with folks trampling on 2.4 with setting their routers to wide bandwidth and not using 5 when possible for that sort of traffic does effect others... I have a neighbor who im not amused with.. but have no authority to say anything about and they dont care anyways..  Building has metal lathe in the plaster as welll...

    WiFiman (by UniFi is of some use - not as detailed as others on a computer)

    Also Net Analyzer (free and Pro) but to be honest they don't do as much as the fingbox due to the iOS APR restrictions

    I use a small but effective app on my MAC at home. I cannot remember the name now but I'll have a look when back.

    I will keep you posted after tonight's check.

    On my Mac I have Chanalyzer but it requires a dedicated Wi-Spy USB arial to work and as mine is quite old and doesn't support 5GHz

    Some AP's have the ability to scan (UniFi that I use for example https://www.ui.com/unifi/unifi-ap-ac-pro/) to find the best channels anti shows graphs of the free ones to use.

    I use NetSpot, which mostly is used on a wireless laptop device.  There's a free version that can display all sorts of information that can help you view and troubleshoot WiFi channel fights.

    I have always used Wifi Analyzer, It's simple and reliable...
    Of course, what @joltdude mention about an "All in one" (showing not only wifi, but also other radius signals) spectrum analyzer would be better, but... xD
    Keep looking up!

    Android: I have a lot apks to analyze wifi signal, but imo best of them is iwscan by evbadroid, every his apks are awesome, for example WiCap is best tool for packet capturing on android.

    Sorry for the delay :-)
    I use this tiny toll:


    it gives in real time SNR and few useful information including , if it is the case, a suggestion for a different channel.

    If you are on a Mac you can just hold Option (alt on old keyboards) and click on the Wifi signal in the menu bar to see loads more info without installing anything.

    Thank you @Jack I know. What I consider an added value for this small app is the advise of which is the best channel in case of need. It helped me a couple of times.
    Cheers,
