We present a theory of Galilean-invariant conventional and chiral p(x) +/- ip(y) fermionic superfluids at zero temperature in two spatial dimensions in terms of a dual gauge theory. Our formulation is general coordinate invariant. The parity-violating effects are encoded in the Wen-Zee term that gives rise to the Hall viscosity and edge current. We show that the relativistic superfluid with the Euler current reduces to the chiral superfluid in the limit c -> infinity. Using Newton-Cartan geometry, we construct the covariant formulation of the effective theory and calculate the energy current.
