Technology
Solar Power
Our solar power module harvests energy from both indoor and outdoor light. Just 1 minute of direct sunlight a day can keep Ray running indefinitely.
Ultra-Low Power Design
We built our own sensors and integrated them with an ultra-low power processor to minimize power consumption while maintaining accurate health monitoring throughout the day.
Advanced Sensors
Ray includes heart rate, temperature, sleep tracking, step counting, and light exposure sensors — all optimized for minimal power consumption without sacrificing accuracy.
Data Privacy
All data is encrypted and stored locally on your device. You control your data — export it anytime, delete it if you want, we never see your personal information.

Design Philosophy
Health tech shouldn't get in the way of living. The Ray is designed to be small, minimal, and needs no user input to function.
Environmentally friendly — no charging accessories, a longer lifespan than other wearables, and a smaller footprint.
Data privacy and openness — your data is for your eyes only, forever. Leave it, export it, delete it; we won't snoop.
Buy once, own forever — no recurring fees, no planned obsolescence.
