Whether and when will the Quad Remesher feature be considered for Android?
The last time I looked for an answer it was doubtful. The issue is that “Android” does not have a set standard infrastructure across the various devices. So the Dev(s) would be buried in development.
I know one person who bought the cheapest Apple they could just to get the remesher. Personally, if I had a need for it (I rarely use Quad Remesher) I port the finished object to Blender to use the addon.
