Dating apps came out at the same time that a lot of others things happen, so you need more to prove causality than coincidence.
I think the correct idea is to look at women's choices as holistic. It's not simply a matter of Man A replacing Man B, C, and D due to hypergamy. It's also Woman X, Y, an Z getting education and good white collar jobs in an unstable economy (a recession started in 2008 that we never really got out of, despite the juking of the stats) and seeing very little value added to them from B, C, and D. There's a LOT more to this than just money, but that's a starting point.
I'm saying that there's more to a relationship than penis in vagina, and women may have replaced Man B's penis with Man A's penis, but Man C and D weren't even disqualified because of their penis, and Woman X and Y replaced Man B, C, and D's non-penis parts through a variety of mechanisms, including an unreasonably good income (modern capitalism is privatized socialism; see Bullshit Jobs by Dave Graeber) as well as things like workout classes, clubs, resorts, and other elaborate activities that are fulfilling enough to someone under (let's say) 40 that simply no men are strictly needed (penis or no penis).
