Lumysi is built as the opposite—a bracelet designed to stay on the wrist through every context, from a workout to dinner, tracking sleep, recovery, heart rate, HRV, activity, skin temperature, SpO2, and more in the background. A multi-wavelength PPG sensor with green, red, and infrared LEDs reads biometrics continuously at 30-second intervals with accuracy comparable to top-tier wrist wearables, while a dedicated skin-temperature sensor detects subtle thermal shifts linked to recovery, cycle patterns, and early illness indicators. Rather than presenting a dashboard of isolated numbers, the AI engine synthesizes multiple signals into a plain-language daily insight—for example, linking lower HRV to a short sleep window and high prior-day activity, and suggesting a lighter recovery day. The bracelet has no screen: health tracking happens silently in the background, and users open the app only when they want to see their data, which eliminates the constant notifications and interruptions that cause many people to abandon wearables. A 5 ATM water resistance rating and hypoallergenic titanium housing mean it handles swimming, showers, sweat, and 24/7 wear without discomfort. The battery lasts up to 7 days and recharges from a small portable case that fits in a bag. The design was created with the product designer behind luxury goods connected to Rolls-Royce, resulting in a bracelet that reads as jewelry more than tech—elegant enough for dinner, comfortable enough to sleep in—and full privacy controls govern all health data.
