Tinder and Bumble would be a lot more effective if you could sniff your potential matches before swiping. Better yet, if you could smell them and hear them. Forget complex matching algorithms—just invent a way to spritz the person's scent while you listen to them talk or read aloud (pro tip: go for “May I Feel Said He” by e.e. cummings, especially if you sound like Tom Hiddleston).
