I think you are overestimating development time on features for apps.
They are all still in their infancy and developers are trying to iron things out for a rock solid foundation before they even start work on developing mod tools for apps.
And I say this as someone who has tested almost all the android Lemmy apps (besides boost since it isn't out yet.).
We MIGHT start seeing Lemmy mod tools in apps by the end of the year or Sometime in winter/spring next year.
But that is very early estimations.
