Don't just track sleep—reshape your circadian rhythm! Circa Accord uses neuroscience, AI coaches, custom NSDR & SOS tools to help you reclaim your energy.Reshape sleep!
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.

It has good features and the price is not expensive at all especially if you compare it with other apps. Still, it provides all the features that you need to track and improve your sleep. One thing I think needs to be improved is the network sometimes isn’t very stable.
Developer Response

Lots to unpack when using Circa accord. This is much more than a traditional sleep tracking app. I like how it goes a layer deeper
We've optimized Circa Accord for iPhone Duo, with improved layouts, smoother interactions, and a more seamless experience across the app.
We've also made performance improvements and fixed minor bugs to keep your daily sleep routine running smoothly.
Sleep with intention. Live in rhythm.
