Lumysi is being unveiled today as a health-tracking bracelet designed to wear like jewelry.
Lumysi is a screen-free titanium bracelet with continuous health tracking and AI-powered wellness insights — built for workouts, workdays, dinners, travel, and sleep. The company is raising money soon in a crowdfunding campaign on Kickstarter.
The health and wellness tracker offers full-spectrum tracking and actionable health insights, all without a screen, notifications, or the look of a fitness device.
The bracelet tracks heart rate, heart rate variability, sleep, recovery, women’s health, blood oxygen and more with no subscription fees. Its titanium housing measures 1.25 inches in length and 0.35 inches in width, weighing just 25 grams total, designed to stay on during workouts, workdays, dinners, travel, and sleep without asking the wearer to compromise on appearance.
The device will come with a lifetime subscription with no ongoing fees for all the early supporters.
“I loved having my health data, but I hated that most wearables only looked good with sportswear. We built Lumysi because that trade-off should not exist. Health technology should be something you want to wear, not something you feel forced to wear,” said Fabiola Hermosillo, CEO of Lumysi, in a statement.
The problem Lumysi was built to solve
The consumer wearable market has expanded significantly over the past decade, yet a consistent behavioral pattern has emerged: the people most invested in their health data are also the most likely to remove their wearable for large portions of the day, Lumysi said.
Smartwatches, with their screens and notification streams, feel out of place at formal events or professional settings. Smart rings, while more discreet, create friction for users who train with weights, rotating on the finger, marking the skin, and losing accuracy during barbell and dumbbell work. Standard fitness bands rarely escape their athletic aesthetic, Lumysi said.
Beyond design, subscription fees have become a persistent frustration across the wearable category, locking core insights behind recurring costs long after the initial purchase. Lumysi addresses both. Early supporters receive full access to AI-powered wellness insights with no ongoing subscription fees. The gap is not a technical one. It is a design one. Lumysi said it was built to close it.
The device
Lumysi’s titanium body houses a suite of biometric sensors that operate continuously in the background. Data is collected passively and transmitted via Bluetooth to the Lumysi companion app for iOS and Android, where it is organized into actionable wellness insights the user can review at any time.
Where most wearables stop at the number, Lumysi goes further. A recovery score of 80% is not just displayed: the app explains what that score is and exactly where the wearer can improve. The data does not just inform. It guides.
Battery life reaches up to seven days between charges, reducing the daily charging friction that interrupts consistent wear on competing devices. The bracelet is rated 5 ATM water resistant, designed for hand washing, rain, workouts, and pool exposure, supporting true 24/7 wear without removal.
The intelligence layer
Raw biometric data has limited value without interpretation. The Lumysi app is designed to address this directly.
Rather than presenting isolated numbers, the app’s AI translates collected signals into plain-language insights that help users understand what their body is communicating. Every data point is accompanied by a single actionable sentence, not just a recovery score, but an explanation of why that score is what it is and where the wearer can improve.
Sleep quality is connected to next-day recovery. Daily activity is connected to overall wellness trends. Changes in heart rate variability are framed in the context of stress, rest, and routine. The goal is for the app to function as a wellness companion rather than a data dashboard.
Early backers receive full access to AI-powered wellness insights with no ongoing subscription fees.
Design and engineering
The Lumysi housing is available in four finishes: Gold, Space Silver, Rose, and Midnight Black. Interchangeable bands are offered in three materials — stainless steel, leather in brown and black, and silicone in white — and are designed to be swapped by the wearer at any time, allowing the same device to move between a gym session, a workday, and a dinner without requiring a device change or any compromise on appearance. Additionally the wearer can change the bands with any other type of band in the market, and not necessarily the Lumysi band only.
