Solara uses the sun's actual position at your location to guide your light exposure, vitamin D, and sleep timing — the three levers that control your circadian rhythm.

The Problem
Your body evolved to sync with sunlight. Screens, artificial light, irregular sleep, and never going outside at the right time have broken that sync — and most people don't even know it.
That 2–3pm slump isn't laziness — it's a circadian timing signal being misread.
Cortisol, your natural alertness hormone, peaks and troughs based on your circadian clock. Disrupt the clock, disrupt your cognition.
Most people are chronically low not because the sun isn't out, but because they're not outside during the right UV window with enough skin exposed.
Light after sunset suppresses melatonin and pushes your sleep window later. Most people have no idea when their biological sleep window actually is.
What Solara Does
Solara uses your GPS and real astronomical data to give you a science-backed daily plan — no wearable required.
Solara calculates the sun's exact position at your location and builds your entire daily schedule around it — sunrise, solar noon, sunset, and everything in between.
Morning light within 30 minutes of waking sets your cortisol and melatonin rhythm for the entire day. Solara shows you exactly when to get it.
Solara identifies your daily UVB window and tracks your vitamin D production in real time based on your skin type, clothing level, and current UV index.
Solar-timed push notifications guide you through your day — from morning sunlight to midday break to blue light warning and wind-down routine.
Solara calculates your optimal sleep window based on sunset and your wake time, so you know exactly when to start winding down — not just when you're tired.
Every feature in Solara is grounded in chronobiology research. This isn't wellness content — it's applied science.
How It Works
Solara uses your GPS to calculate the sun's exact position. No manual entry needed.

Set your skin type and clothing level. Solara calculates your UV production rate in real time.
Solar-timed notifications guide you from morning light to wind-down routine.
"Medical school taught me almost nothing about circadian rhythm. It's arguably the most important system in the human body — for metabolic health, hormonal balance, immune function, and longevity. I built Solara to fix that gap."
