Gut
Spot your trigger foods
Some foods sit fine; others don't. Throne watches how your gut responds day to day and surfaces the patterns — so you can connect what you eat to how you feel and adjust with confidence.
- See your gut response over time
- Spot patterns you'd otherwise miss
- No food diary required
Hydration
Hydrate smarter
Most people run low on water without realizing it. Throne reads your hydration signals automatically and gives you a simple daily score — plus a gentle nudge when you're trending dry.
58% of members improve their hydration habits in their first two weeks.
Habits
Understand your habits
Regularity is one of the clearest windows into gut health. Throne quietly tracks your patterns and shows what's normal for you — so changes are easy to notice early.
Peace of mind
Know your normal.
Most changes in your body happen slowly, long before you'd notice them. Throne learns what's normal for you and shows you when things start to drift, while they're still small.
Where it fits
The missing layer in your stack.
You already track your sleep, heart, and steps. Throne adds the one signal they're missing — your gut.

Core
The gut layer
You already track sleep, heart, and steps. Throne adds the one signal they're all missing — your gut — and turns it into clear scores that sit right alongside the rest of your stack.
Trends
Patterns over time
One reading is a moment; a month of readings is a story. Throne keeps a quiet history of your gut, hydration, and urinary signals, so the slow shifts become easy to see — and easy to act on while they're still small.
- Weekly and monthly views
- Your baseline, learned automatically
- Gentle flags when things drift
Coming soon
Wearable sync
Throne will sync with the wearables you already wear — bringing your gut data together with sleep, activity, and recovery for the full picture.
We'll let you know the moment it's ready.
Privacy
The camera faces
down. Always.
It sees the bowl, nothing else. Your data is encrypted and never shared without your permission.
- Faces down — sees only the bowl
- Encrypted end to end
- Never sold, never shared — the data is yours

What is Throne?
Throne is the first health tracker for the one place your body already gives you a daily report: the bathroom. Throne One is a small smart sensor that clips onto your toilet rim and turns every visit into wellness insights; no wearables, no logging, nothing new to remember. You just sit down like you always do.
-
What does Throne do?
Throne measures four dimensions of your wellness, gut health (stool form and frequency via the clinically established Bristol Stool Scale), hydration, urinary flow, and your bathroom habits, and turns them into simple scores and trends in the app. For the full breakdown of every score, visit our Support page.

Can my whole household use one Throne?
Yes! Throne is built for shared bathrooms. Up to six people can use one device, recognized automatically when their phone is nearby or with a press of their personal button. Each person has their own account and membership, and each person's data is completely private, visible only to them.
