Unlike Nordstr\\\"{o}m's \"massless\" theory, massive scalar gravities are strictly Special Relativistic, being invariant under the Poincar\\'{e} group but not the conformal group. Geometry is a poor guide to understanding massive scalar gravities: matter sees a conformally flat metric, but gravity also sees the rest of the flat metric, barely, in the mass term.
