MK Engineering, LLC is a small engineering and scientific software company founded by Matthew Kupinski, Professor at the University of Arizona Wyant College of Optical Sciences. The company focuses on building practical tools for measurement, analysis, documentation, and scientific communication.

Its first app, Tares, is a private, on-device strategy analyzer for five-letter word puzzles like Wordle. Tares helps players enter board clues, compare remaining answers, review entropy-based recommendations, and understand why certain guesses are stronger than others. Future products, including FieldReport, will expand this mission by making it easier to capture observations, generate reports, and preserve technical context from fieldwork, lab work, and engineering projects.

Beyond software, MK Engineering, LLC reflects a broader curiosity about science, optics, imaging, instrumentation, and the useful little details that make technical work more understandable. The company aims to create tools that are precise enough for serious work, simple enough to use regularly, and grounded in the habits of good scientific practice.
