WiFi Signal: Strength Analyzer für Mac

Well, I've tested this out for an hour.
It's not something I need so I uninstalled it.

The only benefit I see is that it can display the info in the menu bar so you don't have to Option-click the Wi-Fi icon to see it.

I'm staying in a hotel right now and there are 4 different signals which use the same name but different BSSID's. Two use channel 4 and two use channel 8 (verified by WiFi Explorer). But WiFi Signal only shows one, and says "no better channels to recommend for this network." That's probably true since I am connected to the strongest one, but I'd still like the option to connect to one of the other signals.
Sometimes at this hotel my Mac has connected to one of the weaker signals and no matter how many times I turned Wi-Fi off/on it wouldn't connect to the strongest one.

There are 16 items you can choose to display. There's no text for most of the items, so you have to know what you're looking at. Right now after the signal name and BSSID # I have 2.4 n 4 20 -57 71 -80 33 22 195 217 23.
It won't display the device name for the hotel's router (WiFi Explorer does), but with everything else showing it's using five inches of menu space (of course no one needs to display all that).
There's no option to show the IP address.

I use WiFi Explorer (https://www.adriangranados.com/apps/wifi-explorer). It costs a bit more but there is a trial version available. If you only need basic information then neither of these apps is for you. But WiFi Explorer tells me a lot more about my WiFi signal than Option-clicking on the WiFi icon in the menu bar does. As for how well WiFi Signal works, we won't know until someone is willing to risk buying it without trying it first and tells us about it. Since the last comment below was made more than two years ago, we may never know—not here, anyway. It is well rated at the App Store, if you want to check it out there.

PS: I just found out (at the App Store) that WiFi Signal and WiFi Explorer are from the same developer. WiFi Explorer, however, does not use the menubar. Other than that, there's no easy way to compare the two, except that Wifi Signal is less expensive and doesn't have a trial version.

So, for $0.99 it does what the FREE applications Signal Strength and WiFiSpy (among others) FREELY do for FREE?

same info you get if you hold 'Alt' (option) key and clickin WiFi icon in menubar and you see same data info about your signal, why you need for that install extra app?
