Stop Sleeping Randomly. Start Sleeping Scientifically. Circa Accord is not just a sleep tracker; it is a Neuro-Circadian Optimization System designed to align your biological clock with the natural world. Based on cutting-edge neuroscience protocols, Circa Accord helps you master the hormonal timing of Cortisol and Melatonin to achieve peak energy during the day and restorative deep sleep at night. KEY FEATURES: Circadian Alignment Protocol: A dynamic daily checklist anchored to your wake time. Know exactly when to view sunlight, when to hydrate, and when to cut off caffeine to prevent the "afternoon crash." AI Neuro-Coach: Chat with Steven (Neuro-Guide), Don (Drill Sergeant), or Linda (Wellness Guide). Our advanced AI analyzes your habits and biometrics to provide personalized, science-backed advice. NSDR (Non-Sleep Deep Rest): Access built-in audio tools for NSDR and Yoga Nidra. These protocols are scientifically proven to replenish dopamine and accelerate neuroplasticity. Red Light Mode: Protect your melatonin. The app interface automatically shifts to a monochromatic red wavelength at night to prevent screen-induced wakefulness. Biometric Integration: Syncs seamlessly with Apple Health (HealthKit) to track HRV, Resting Heart Rate, and Sleep Duration, giving you a daily "Readiness Score." Insomnia SOS: Can't sleep? Activate the SOS module for guided 4-7-8 breathing and anxiety-reducing dialogue to calm your nervous system instantly. THE SCIENCE: Light is the primary zeitgeber (time-giver) for the human brain. Circa Accord leverages timing—of light, temperature, and food—to anchor your circadian rhythm, ensuring you wake up alert and fall asleep effortlessly. PRIVACY FIRST: Your health data belongs to you. Circa Accord prioritizes local storage and on-device processing.
