Description by Ceren Tunay Written by the developer, not by AppBrain. Click to read.
Circadian Time is a calm daily rhythm coach designed to help you feel better through better light timing, better outdoor habits, and smarter sun decisions.

Your body responds to light all day long. The right daylight at the right time can support mood, morning energy, and a steadier daily rhythm. Circadian Time turns that into something simple and usable.

Instead of overwhelming you with science, Circadian Time gives you a clear daily plan:

when to get early daylight
when to step outside for a short reset
when to slow bright light down in the evening
how your rhythm is trending over time
when sun exposure looks calmer or more risky
how to think about tanning and burn risk more carefully
What you can do in the app:

get a personalized Circadian Score
see your ideal daylight windows
log sunlight exposure
complete morning and evening mood and energy check-ins
follow simple daily guidance
track consistency across the week
monitor streaks, outdoor goals, and recovery suggestions
check sun balance guidance, estimated UV risk, and tanning-aware recommendations
unlock premium reminders and deeper insights
Circadian Time is built for people who want a cleaner, calmer way to support:

mood balance
morning energy
daily rhythm
outdoor consistency
smarter sun behavior
Premium unlocks a deeper layer of guidance with smarter reminders, richer insights, and a more personalized rhythm experience.

Important note:
Sun and UV guidance inside the app is designed as supportive wellness guidance and does not replace professional medical advice or official real-time weather safety alerts.`
