## Description

Wake with the sunrise, catch your daily light, and never forget your blue-light glasses at sunset — all on autopilot. Build a healthier rhythm that actually lasts.

Your body runs on a 24-hour clock, and light is what sets it. Circadian helps
you work *with* that clock instead of against it — wake near sunrise, soak up
bright light during the day, and protect your evenings — so you sleep better,
feel more energized, and build a rhythm that actually lasts.

It runs quietly in the background and adjusts to the sun at your exact location,
every single day of the year. No guesswork, no manual updates.

WAKE WITH THE SUN
Set an alarm relative to sunrise — 20 minutes before, right at sunrise, your
choice — and it automatically shifts earlier and later as the seasons change.
You wake with natural morning light instead of an arbitrary number on a clock.

PROTECT YOUR EVENINGS
A gentle reminder fires before sunset (15 minutes by default, adjustable) to put
on your blue-light blocking glasses. Cutting evening blue light helps your body
wind down naturally and protects your sleep.

TRACK YOUR LIGHT
Start a Light Session when you step outside and Circadian measures your light
exposure, scoring it by brightness, duration, and time of day. Going for a walk?
Take a quick reading and pocket your phone — hands-free mode keeps tracking your
time. Hit your daily light goal and watch it add up.

BUILD THE HABIT
A simple daily check-in — "Did you catch the sunrise?" — keeps your streak
alive. See your weekly and monthly consistency at a glance, and let small daily
wins compound into a real routine.

WORKS OFFLINE
Sunrise and sunset times are calculated on your device using your location — no
internet required after setup. Your data stays on your phone.

COMPLETELY FREE
Every feature is unlocked for everyone. No subscription, no in-app purchases, no
ads, and no third-party tracking.

Your circadian rhythm is the foundation of your sleep, energy, and mood. Start
building it today — one sunrise at a time.
