Why this matters now
In the past decade, continuous health monitoring has gone from niche to mainstream – one in six Americans checks a wearable device every single day. Fitbit taught us that step counts matter. Apple Watch proved that a wrist can double as a heart monitor. WHOOP and ŌURA showed us the power of sleep and recovery metrics.
While sleep, exercise, heart rate, blood oxygen, and more are now tracked in real time, two of the cornerstones of human health remain largely unmonitored: gut health and hydration.
This gap matters. Your gut is the engine of your wellbeing, affecting everything from mood and metabolism to long-term disease risk. Hydration impacts cognition, energy, digestion, and even drives fall risk in older adults. Compared to the level of daily insight we have into the other corners of our body, the state of the art for gut health and hydration is back in the dark ages.
If you’ve ever been tested your stool or urine, you probably know what that looks like: manual collection of samples from the toilet. Unpleasant, to say the least. These tests certainly have their place — they can capture things you can’t get from daily monitoring — but they’re far from the continuous, effortless insights that modern consumers expect.
We saw an opportunity to change that. Throne One could never have been the first consumer health device. The world wasn’t ready for cameras in the toilet. But after two generations of wearables have educated people on the value — and joy! — of daily health insights, the world is finally ready to bring this same mindset to gut health and hydration.
Your gut is the final frontier. Throne is here to illuminate it.
Meet the Throne One: the world’s first continuous gut health monitor
The Throne One is the first device in history to transform your bathroom routine into a seamless stream of health insights. We call it the wearable for your toilet — because like a wristband or a ring, it works in the background to monitor your health every single day. And just like the best wearables, Throne is designed to be effortless: simple to set up, intuitive to use, and easy to keep charged so it’s always ready when you are. You just live your life, and Throne captures the data.
Here’s what sets Throne One apart:
- Hands-free: It fades into the background of your bathroom routine.
- Continuous: Every session becomes a health check-in.
- Multi-user: One device supports every member of your household.
- Doctor-trained AI: Built on medical research and clinical guidance, focused on the same health metrics doctors care about.
- Privacy-first: Designed for one of the most intimate, sacred spaces in your home.
This is the first time gut health and hydration can be monitored as continuously and seamlessly as sleep or steps. And that makes Throne One not just a product, but a platform — a foundation for a new era of health monitoring.
What Throne One tracks today
Gut Health Score
Your gut tells a story every day. Throne translates that story into a single, trackable number: the Gut Health Score.
This score is built from your digestive pattern, which accounts for:
- Frequency: How often you poop.
- Consistency: Classified by the Bristol Stool Scale – the medical gold-standard for describing stool texture, ranging from hard, to healthy, to loose, to liquid.
Together, these two markers create a snapshot of your digestive rhythm. Throne tracks them session by session, then summarizes them in your Gut Health Score. The result: you can finally see trends over time, understand how diet, stress, and lifestyle impact your gut, and make choices that improve your digestion.
Here are examples from my own personal Throne data. Can you guess which month was more stressful?
Hydration Score
Hydration underpins almost every function in your body. Even mild dehydration can sap energy, cloud your thinking, slow digestion, and put stress on your kidneys. Consistently poor hydration has been linked to cognition and mood, increased risk of kidney stones, constipation, and accidental falls in older adults.
Until now, accurately measuring hydration in daily life has been almost impossible. There are high-tech patches that analyze sweat, but those are designed for performance athletes during workouts. But hydration matters far beyond the gym – that’s why Throne created the Hydration Score.
By analyzing urine color and concentration, Throne estimates hydration status and translates it into a simple, actionable score. You’ll see it change throughout the day, improving when you drink more water, declining if you’re not replenishing enough.
“Drink more water” is good advice. Seeing your Hydration Score reflect when you do it is proof.
Urinary flow health
Urinary dynamics tell a powerful story, especially for men’s health. Changes in flow — whether slower, weaker, or more interrupted — are a natural part of aging, and nearly all men experience them over time. Throne One uses acoustic sensing to measure flow rate and duration, giving you insight into Urinary Flow Health.
At launch, this feature works only when users pee standing up, since the sound of urine entering the water is critical to accurately measuring flow dynamics. We’re working on bringing this feature to everyone!
This is a breakthrough area of continuous monitoring, and it adds a new layer to understanding how your body is functioning.
Design philosophy
Of course, none of this matters if the product isn’t usable. Bathrooms are intimate, sacred spaces. The bar is higher here than anywhere else. We knew Throne had to be much more than functional. It had to be discreet, intuitive, respectful, and even beautiful.
That’s why Throne is designed to feel effortless, detecting sessions automatically without any fiddling or friction. It supports multiple users within a single household, making it as inclusive as it is intelligent. It is privacy-first by design, with all session data anonymized, protected, and controlled by you. Above all, it’s built with deep reverence for the user – a thoughtful product to make life easier, especially on hard days. For people living with chronic gut issues, bowel patterns can dictate the rhythm of daily life. Throne is made to bring clarity and calm in the moments that matter most.
We’re incredibly proud of what we've built. The device itself elegant, reliable, and designed to disappear into your life, while the beautifully designed app gives you daily insights that are impossible to ignore.
Where we’re headed
The cultural tide is shifting. Google Trends data shows that gut health has surpassed sleep health as a search topic. People everywhere are waking up to the importance of the microbiome, digestion, and hydration. Throne One is just the start, and what comes next is even more exciting.
In the months after launch, we will introduce a scoreboard for your diet – a tool that helps you see how the ingredients you eat impact your gut health in real time. For people managing dietary sensitivities, triggers, or intolerances, we believe this will be a game changer. Most people are not willing to endure an elimination diet for long enough to reach meaningful conclusions. Throne will make those critical insights possible without the frustration.
In the year after launch, we’ll be kicking off research projects with partners at leading institutions, leveraging Throne’s continuous, real-world stream of gut health and hydration data. This work will help unlock new insights into how the body functions and drive breakthroughs in our understanding of human health. As a Throne user, you’ll have the option – but never the obligation! – to participate in this research.
Ultimately, our long-term vision is to become the smoke detector for colon cancer. Roughly 1 in 25 Americans will develop colorectal cancer in their lifetime, and for those born after 1990, the risk is even higher. Last year alone, 153,000 Americans were diagnosed with colorectal cancer, and a third died – more deaths than from all car accidents combined.
The difference between life and death is timing. Throne’s vision is to shift that timing by detecting microscopic blood in stool early, when treatment is most effective. Just as there’s a smoke detector in every home, we believe every bathroom will one day have a Throne.
