About CronoLux

Your eye has cells that don't form images. Their only job is to detect the exact frequency of dawn (480 nanometers) and tell your brain it's time to wake up. Without that signal, your biological clock doesn't start properly. CronoLux gives it that signal.
Developed by a biochemist, CronoLux delivers morning light sessions in the 480 spectrum, the peak sensitivity of the retina's ipRGC cells, to help synchronize your circadian rhythm and improve how you feel from the moment you wake up.

HOW IT WORKS
Each session is structured in three phases designed to work with your biology, not against it:
· Breathing activation: a guided breathing exercise to ease your nervous system into the day. No need to stare at the screen. Simply place your phone nearby and let the light reach you naturally.
· Daily content: a curated card with science, philosophy or curiosity designed to engage your mind while your body receives the light signal. A different card every day.
· Reflect: a brief moment to set your intention for the day and log how you woke up. Over time, you'll see patterns in your morning energy.

KEY FEATURES
· Circadian light sessions from 5 to 30 minutes
· Adjustable intensity levels
· Multiple custom protocols with scheduling
· Daily streak tracking to build the habit
· Science section with light spectrum visualization and key references on ipRGC biology and melatonin regulation
· Available in English and Spanish
· No ads. No subscriptions.

WHO IS IT FOR
· People who work indoors without access to natural light
· Shift workers or early risers who start before sunrise
· Residents in northern latitudes with low seasonal sun exposure
· Frequent travelers dealing with jet lag
· Anyone interested in sleep quality, morning routines and science based wellness

THE SCIENCE
The ipRGC cells in your retina are sensitive to light around 480nm, the wavelength characteristic of natural dawn. When stimulated, they signal the suprachiasmatic nucleus to suppress melatonin production and advance the circadian phase. CronoLux is built on this published research, not on marketing claims.

CronoLux is a personal wellness tool based on published research on circadian light stimulation. It is not a medical device and does not replace professional health advice.
