Throne
Smart Toilet Sensor for Gut Health & Hydration Tracking
Throne is a small sensor that clips onto the side of your toilet. Every time you use the bathroom, it checks your poop and pee and sends the results to an app. Over time you can see how what you eat and drink, and how you sleep and live, affect your digestion and hydration.
What you’ll see after every visit
A report card with your stool consistency, color, volume and diameter, how often and when you go, and your hydration based on your urine concentration. Each result is compared with your normal, so changes are easy to spot.
Will it fit my toilet?
Throne is designed for most standard residential white toilets with a rim thickness up to 2.25 inches, and works alongside many bidet setups. It clips on without tools or plumbing.
What does membership include?
Unlimited gut health and hydration tracking, your Journal, Gut Health Coach, data export, and tracking across multiple Throne devices, for $6/month per member. Cancel anytime.

What members are learning.
“I am deeply invested in my health, hydration, and how my body responds to what I eat, but like most people I was often just guessing when it came to what was actually going on with my gut. Throne completely changed that for me.”
Shelby G., App Store review
“I’ve had long-term mild GI issues and started working with a nutritionist who had me try a low-FODMAP diet. I came across Throne and thought it would be a good tool to help quantitatively track whether it’s working. And the good news is that it seems to be!”
Ian B., Throne member
“There is a feeling of confidence when I get the report after I use the bathroom.”
Sanjiv D., Throne member
“Something I’ve learned already in one week of using Throne is that I get very dehydrated after I drink my coffee… I’m building a new habit so quickly that I wouldn’t be able to do from a lab test.”
Lauren & Renee, Biohacker Babes

More questionsDo I have to log every meal?
No. Throne tracks bathroom visits automatically at the toilet where it’s installed. Add food, symptoms, or life context in your Journal when it feels relevant. Some context from ordinary days makes comparisons more useful.
What if there isn’t a clear pattern?
What you can learn depends on your history and Journal context. Sometimes there won’t be a consistent connection to point to. Your record still shows what happened and what remains unclear.
Does Throne detect blood?
No. Throne does not detect blood. If you notice blood in your stool or urine, talk to your doctor.

Throne is designed for most standard residential white toilets with a rim thickness up to 2.25 inches.
