HueDx

HueDx is a Philadelphia diagnostics company - formerly Group K Diagnostics - that turns any smartphone camera into a reader for lab-grade, quantitative color-based tests. Its patented HueCard color-correction hardware and AI-powered HueTools/HueCloud software let researchers develop, validate, and deploy paper-based colorimetric assays without proprietary readers or lab infrastructure, aiming to make quantitative results available at the point of care and at home.
