One of my very best friends lives in another country. We speak nearly every day, but I haven't seen them in person in over a year.
Another of my friends lives on the other side of the USA. We speak a few times a week, but I haven't seen them in person in about four years now. And that was only because their mom lived nearby. His mom moved, so it's unlikely we'll see each other except once a decade when we do our friends trip to Vegas.
I have other very close friends who I almost never see in person.
My point being, having to tap phones is cool and all but not a great measure of the strength of friendship.
