Why This Matters
Light affects every aspect of our biology—from sleep cycles to skin health, from mood to metabolism. Yet most of us navigate our light environment blindly, missing opportunities to optimize our wellbeing through informed exposure.
We're building the first tool that makes light visible, quantifiable, and actionable in your daily life.

Questions
We're planning a public launch in Q2 2026, with beta testing beginning in Q1. Join the waitlist to be among the first to know when beta applications open.
This is the first wearable device specifically designed to quantify light exposure for health optimization. While other devices track activity or basic biometrics, we focus exclusively on light—the most underestimated factor in human wellness.
We're targeting a retail price in the $200-300 range. Early waitlist subscribers will receive exclusive early-bird pricing when we launch.
Yes. Waitlist subscribers receive monthly development updates, early access to beta testing, and first notification when we launch. We respect your inbox—no spam, just meaningful updates.
Beta testing applications will open to waitlist subscribers first. We'll select participants based on use case fit and geographic distribution to ensure diverse testing conditions.
The device uses medical-grade light sensors to continuously monitor UV, visible, and infrared light exposure. Data is processed through our proprietary algorithms to provide personalized insights about circadian timing, skin health, and optimal light exposure patterns.
