Throne Science is a smart toilet sensor that tracks gut health, hydration, and urinary function automatically with every flush. A discreet sensor attaches to any standard toilet and, combined with Throne's AI-powered companion app, surfaces continuous patterns in digestive health, hydration status, and urinary function every day. The data accumulates passively and presents itself as accessible, actionable observations rather than clinical readings. Throne's long-term mission is to build the first at-home, continuous screener for early signs of colorectal cancer and cancers of the urinary tract.
