Why does your interaction with the app end with the messaging thread? It feels like every app decides that once you've been "connected", that's the end of their responsibility.
I'd like to see an app that takes a more holistic approach: A good algorithm gets you connected, allows you to communicate but also helps set up the first (and second? or third?) date(s). Then gathers feedback on the dates -- what went well, what didn't, and uses that input to refine the matching algorithm (if necessary).
The key here is that the current crop of apps aren't really "dating" apps - they're "first introduction" apps. Getting involved in the whole process could (maybe?) lead to better outcomes.
This is of course assuming that the goal is better outcomes -- as other commenters have pointed out, some companies don't actually want that, they just want you endlessly scrolling (and subscribing). But assuming you build a business that does truly want to optimize for successful outcomes, this could be a start...
