Yes, exactly, and that kind of analytical approach (i.e.: identify specific steps to "solve problem") is less common than some people, especially the kind of analytical people who comment on HN, think.
Further, as commenters above have said, making an app a part of your problem solution is an even narrower funnel. Some people might just go straight to "make some new friends", "join a club", "get involved politically", or whatever.
Meditate, see a therapist, exercise more, talk to a doctor...the mindset that says "I have a problem, I will search for an app to fix it" is vanishingly small, except within one thin demographic slice, where it is overwhelming.
