Tinder icon on top of screenshot?

Friend of mine we were boys in high school and college, he sent me a prefantasy football line up as we were discussing our leagues. At the top of his screen shot there was an icon of the app Tinder. He just got married last year, and things look to be great. Beautiful wife he has as she is a school teacher and yoga teacher. He is firefighter but high rank and also a physical trainer. When I was single I had tinder so I know the icon when I see it. How do I go about this? Man my heart started racing when I seen that icon. He doesn't know that I noticed it
