Wi-Fi signal strength detector app
A while ago someone posted details of an app that beeps as it detects the proximity of a wi-fi signal.
I tried it, loved it, then, foolishly, I uninstalled it when I thought I didn't need it anymore.
You can all guess what's coming next, can't you?
I've searched all the possible terms I can think of, but can't find the post/thread. If anyone remembers what I'm talking about, please post a link or just the name of the app, top earn my (almost) undying gratitude.
Thanks in (sweaty) anticipation.
