Which way should my TV antenna point for best reception

I installed this app on my smartphone to use it as a pointer:
Antenna Pointer
I use this site to input my address to see what channels are in range, and to get the direction in degrees:
TV Fool Reception Guide

Then simply adjust the antenna to match the direction of the pointer in the Antenna Pointer App. Don't sweat it if you have your (VHF) antenna pointed backwards, it will still get nearly the same FM signal. Just don't try that with the UHF antenna, It's like "wearing your (bow) tie backwards, LOL. :B
