Even if you can't see them, lights that disrupt your rhythm are hidden everywhere. We analyze your environment to show you exactly how these lights are distributed in your space.

Instantly apply lighting optimized for immersion in whatever you're doing—whether it's reading, relaxing, or focusing.
3. Custom Fine-Tuning
Delicately adjust the brightness and color temperature to find the most comfortable setting for your eyes, exactly when you need it.
4. My Light Favorites
No need to adjust the settings every time. Save your frequently used lighting modes and access them instantly.
5. Natural Light Alarm (Wake-up/Sleep)
Fall asleep naturally and wake up feeling completely refreshed with our stress-free light alarm.
