I'm looking for a way to map my network dead spots. Are there any marketplace apps that display a signal strength meter to assist in something like this? I've looked at TestMyNet but it only seems to scan one time on demand, it's not really a meter. I'm basically looking for Android's WiFi Analyzer for Windows Phone
The current SDK does not allow that type of access. Sorry, but there is no app for it, and I am pretty sure no homebrew app exists either.
The only place I can see WiFi strength is in the WiFi Settings. Where you can see every WiFi network and the signal strength.
With the introduction of Windows Phone 8.1 you can see the strength right there near the carrier signal.
