This, this in spades....
I use an app on my android phone when setting up my scopes & get wildly varying results!! When setting up my lx90 near enough seems good enough for an az/alt mount but, when setting up my eq mount for either visual or imaging I can be off by as much as 10* & it makes a huge difference to getting alignment & PA!! On occasion I have had frustrating nights both with alignments & then PA, sometimes not really achieving PA at all because the initial setup is too far off!!
I've been considering buying a proper compass but, I saw the post about pavers earlier & am going to investigate that further.
