What if you don’t have a smart phone? Or hell, what about one that’s 5+ years old? Are they just SoL?
I have a smart phone and generally against telling people how to host their events... but requiring smart phones with tracking apps on them to do X or Y for the "pursuit of progress" is pretty dystopian.

Remember, that you want something from them (entering the country). They can refuse you if they don't like your old-fashioned lifestyle.
On a more serious note: “Shit/Sorry, Outta Luck!”
