About Circadian Time:Mood, Light,Sun
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.` Keywords circadian sunlight daylight uv sun exposure mood energy rhythm wellness routine outdoor tanning Privacy Policy: https://docs.google.com/document/d/1AelyeY3YnNNG_nYc10zg0BLPxYMlK74D5ZN-Xqs6Phk/edit?tab=t.0 Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
