PureDigest

PureDigest is pioneering a non-medical, at-home breath testing device that enables users to track fermentative gut gases like hydrogen (H₂), methane (CH₄), and hydrogen sulfide (H₂S) on a daily basis. Unlike conventional medical diagnostics, PureDigest empowers individuals with real-time insights into their digestive patterns and food responses — with a sleek, connected device and an intuitive mobile app. Currently in the final prototyping phase, the product is designed for wellness and self-tracking use, especially for individuals with suspected food intolerances, SIBO-like symptoms, or IBS. The companion app visualizes fermentation trends, highlights patterns, and supports export of key metrics for healthcare discussions.
