Don’t waste money on fancy signal finders. This works!
I was looking on Amazon and Walmart for a signal finder. Prices varied from $25 to $100+ with mixed reviews. I found this app again with some mixed reviews but for only $2 I thought I would give it a try. I used the compass to position my cheap indoor antenna. I went from having only 7 channels in the bedroom to almost 50. I did the same in the living room which seemed to be doing better and I went from 30ish channels to almost 50. This $2 has saved me a lot of money as I was even considering prior to this getting an outdoor antenna professionally installed. In addition to all the extra channels all the ones I already had are showing so much clearer and are not randomly scrambling.
