Throne translates your gut, hydration, and flow signals into guidance you can act on. Make sense of your bathroom signals with hands-free tracking and easy daily scores. DAILY SCORES Gut Health, Hydration, Bathroom Habits, and Urinary Function give you a clear view of how your body is running today, plus guidance on what to do next. SEAMLESS BY DESIGN Hands-free tracking that fits your normal routine. Downward-facing sensors and doctor-trained AI translate what happens in the bowl into easy-to-read trends. BEST-IN-CLASS PRIVACY Records only when your phone is nearby or when you push your assigned button. Data is encrypted. You’re in control of what’s saved and shared. GUT HEALTH Build a record of stool form, frequency, and timing so you can connect meals, stress, and routine to how you feel. A weekly Gut Health Score makes progress simple to track. HYDRATION See color-based trends that reflect your true hydration, often before thirst kicks in. Learn how daily swings, activity, heat, and electrolytes move your Hydration Score. BATHROOM HABITS Time your sessions end-to-end to support healthier habits. Track active time, wrap-up time, and overall duration to help reduce pelvic-floor strain and promote regularity. URINARY FUNCTION For users who pee standing up, Throne estimates flow patterns from sound to help you notice changes in peak flow, average flow, and volume over time.* LONG-TERM TRENDS Find your normal in about two weeks. Spot meaningful shifts early and make small adjustments that stick. WHY IT MATTERS Dehydration, irregularity, and urinary changes are common and often missed. Throne makes these systems visible and trackable every day so you can act sooner and feel better. *Urinary Function currently available for standing voids. The Throne App requires a Throne device. Throne is not a medical device and does not diagnose, treat, cure, monitor, or prevent any disease or condition. Do not change medications, diet, or routines without consulting a healthcare professional.
