The KArlsruhe TRItium Neutrino (KATRIN) experiment is designed to measure tritium β-decay spectrum with enough precision to be sensitive to neutrino mass down to 0.2eV at 90% Confidence Level. After an initial first tritium run in the summer of 2018, KATRIN is taking tritium data in 2019 that should lead to a first neutrino mass result. The β spectral shape of the tritium decay is also sensitive to four countershaded Lorentz Violating (LV), oscillation-free operators within the Standard-Model Extension that may be quite large. The status and outlook of KATRIN to produce physics results, including in the LV sector, are discussed.
