The operant word is expect — not desire or deploy. I might think that such an app (whether needed now or not) would be a desideratum, but I wouldn't a priori guess that such might be available and therefore go looking for such.
I think the phrase "there's an app for that" is quite pervasive and true. Pretty much anything one can think of probably has an app related to, derived from and/or associated with it.
Of course this does not mean they are all quality apps, let alone needed apps. But my point is, you
can a priori guess that such might be available.
