We love health tracking. We just never loved what health trackers looked like.
Most wearables feel great at the gym and completely out of place everywhere else. Sooner or later, they get taken off, and once that happens, they’re often forgotten. We wanted something different.
Lumysi is a wellness bracelet designed to give you meaningful health insights while looking and feeling like a piece of jewelry. It tracks sleep, recovery, heart rate, HRV, activity, temperature, SpO2, and more, so you can stay connected to your health without wearing something that looks like a gadget.
Wear it wherever life takes you.
And as our early supporters, Kickstarter backers get a lifetime subscription for FREE
Lumysi was designed around a simple idea: if you’re going to wear something every day, it should be something you genuinely love having on your wrist.
Comfortable enough to sleep in. Elegant enough for dinner.
We obsessed over every detail and partnered with the designer behind luxury products connected to Rolls-Royce to create a health bracelet that feels more like jewelry than tech.
But while we refined the design, we never compromised on what matters underneath: the sensors, the data, and the health insights that make Lumysi a powerful wellness companion.
Because health technology can be powerful and beautiful.
While you work, sleep, train, and move through life, Lumysi is tracking everything that matters.
Heart rate, HRV, sleep, recovery, body temperature, SpO2, activity, and cycle tracking and more. All happening quietly in the background while you go about your day. You need to just wear it and admire it.
Over time, the data builds up into something genuinely useful, patterns that tell you how your body is actually responding to your sleep, your stress, your movement, and your lifestyle.
Most trackers give you a number and leave you to figure out the rest.
Lumysi goes further. Instead of showing you a dashboard of isolated metrics, it connects your sleep, activity, recovery, and wellness signals into one simple daily picture.
For example: not just “HRV: 52”, but “Your HRV is lower than your 7-day average. You had a shorter sleep window last night and high activity yesterday. Your body may benefit from a lighter day.”
You get context and direction. You get something you can act on.
Lumysi uses a PPG sensor with green, red, and infrared LEDs, the same technology trusted by Apple Watch and WHOOP, to continuously read your heart rate, HRV, and blood oxygen levels with genuine precision.
A dedicated skin temperature sensor quietly tracks your body’s thermal baseline around the clock, surfacing subtle shifts that connect to recovery, cycle patterns, and early signs of illness.
An accelerometer captures every movement: steps, activity, and the stillness that tells the story of your sleep. Every sensor refreshes your data every 30 seconds. This is real, continuous, precise monitoring that builds a picture of your health you can actually trust.
We made a deliberate choice with Lumysi.
Lumysi is completely screen-free: silent, calm, and designed to stay out of your way. Because most wearables come with constant reminders, notifications, and things to check throughout the day.
Lumysi tracks your health in the background. Whenever you want to see your data, simply open the app.
Backing Lumysi on Kickstarter comes with a benefit that won’t be available after the campaign: lifetime access to all Lumysi features and AI-powered wellness insights, with no subscription fees.
That means every morning insight, every plain-language explanation of your data, and every personalized recommendation is yours from day one, without paying anything beyond your backing amount.
No monthly fees. No subscription required. Just a Kickstarter-exclusive benefit for the people who helped bring Lumysi to life.
Lumysi is designed to stay on through every part of your day, giving you a more complete picture of your wellbeing.
Lumysi lasts up to 7 days on a single charge. A full week of heart rate, HRV, sleep, activity, temperature, recovery tracking and more. All without touching a charger once.
Charge it at the start of the week and keep tracking through the weekend.
When the battery runs low, simply place Lumysi in its portable charging case. The case is small enough to carry in your bag and gives you an extra charge when you’re away from home.
You should never have to think about whether you can wear your health bracelet right now.
How often do you take off your wearable? For a shower. A swim. A workout. Before bed.
Lumysi is designed to remove those interruptions with 5 ATM water resistance, meaning it’s built to handle swimming, showers, sweat, and everyday life, plus a hypoallergenic titanium housing that’s comfortable enough for 24/7 wear.
A ring rotates during a deadlift. It scratches against a barbell. It marks your finger after hours of wear. And the moment it becomes uncomfortable, it comes off, taking your data with it.
Lumysi sits on your wrist. It does not rotate, scratch, or interfere with your grip. It stays exactly where it needs to be, through lifting, swimming, sleeping, and every moment in between.
And the longer it stays on, the better the picture it builds of your health. Consistent wear means consistent data. That is where the real value is.
When it comes to health data, privacy matters.
The information Lumysi collects is encrypted and stored securely, so your personal health data stays protected. We don’t sell it, and we don’t share it with third parties.
It’s your data, and it should stay that way.
Lumysi makes a genuinely meaningful gift for a parent, a grandparent, or anyone whose health you think about from a distance. This is an elegant bracelet they will actually want to wear, that quietly tracks their heart rate, sleep, recovery, and activity every single day.
A gift that looks good on their wrist and can give you peace of mind.
Opening the Lumysi app should feel like checking in with someone who actually knows your body.
Every morning you get a clean, simple overview of how you slept, how recovered you are, and what your body needs today. Everything in plain language, easy to read in seconds.
Every metric comes with a one-sentence AI explanation, why your score is what it is and what to do about it. Sleep, HRV, activity, temperature: all connected into one clear daily picture.
Available on iOS and Android.
We designed Lumysi to feel like yours from the moment you put it on.
Choose your housing finish: Gold, Rose, Midnight Black, or Silver Space. Then pick your band: stainless steel 316L for a polished everyday look, leather in brown or black for something warmer and more personal, or silicone in white for active wear.
Every configuration fits every wrist size. Because Lumysi was designed for everyone.
We are Fabiola, Alfonso and Miguel, a team bringing together expertise in product design, hardware, software, AI, and engineering to create a different kind of wearable.
Each of us brought a different piece of the puzzle. Hardware, engineering, artificial intelligence, product design, manufacturing, and user experience.
What brought us together was a shared belief that health technology doesn’t have to look or feel like technology.
We’ve spent countless hours designing, prototyping, testing, and refining Lumysi. Every decision, from the hardware architecture to the shape of the bracelet, was made with the same goal: creating a wearable people genuinely enjoy wearing.
Today, Lumysi is the result of that collective effort.
