Interesting method but I’d question its accuracy ( not the app’s accuracy within the phone but the resultant shadows accuracy with respect to the pole
I’m still using a stick and the sun at solar noon , never fails and gets me to within a few degrees of the pole ready for a polar alignment routine to get below an arc minute anywhere.
Thanks for posting
