Tinder
Tinder is designed for smartphones and is popular with people my age. I downloaded it for fun (and research!) on a recent vacation to Australia and continue to receive matches from guys in Australia and New Zealand. Too bad I live in the USA; although, there is one guy who wants me to get him a green card.
I did manage to line up a handful of American Tinder dates! Warning: Be careful what you wish for when you swipe right because your date may end up looking or smelling like yesterday’s sidewalk garbage.
