Circadian Rhythm Companion

Circadian Rhythm Companion helps support more energy during the day and better sleep at night with simple daily actions based on your local light. It helps your body know when to wake up, stay alert, and wind down. Use it to see where you are in the local day, choose simple morning light and sunset actions, keep caffeine inside a cleaner rhythm, and prepare one cue for tomorrow without turning wellness into a dashboard. The app is private by design: no account, no ads, no social feed, and no external analytics SDK in the current App Store version. Location is used to calculate local solar timing, and you can choose device location or a manual city. Circadian Rhythm Companion is wellness rhythm support. It is not medical care, diagnosis, treatment, emergency support, UV exposure guidance, vitamin D guidance, burn-risk guidance, or skin-exposure coaching. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Purchases, trials, cancellations, refunds, and subscription management are handled through Apple StoreKit and your App Store account.
