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.
PRIVACY FIRST:
Your health data belongs to you. Circa Accord prioritizes local storage and on-device processing.

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
Thanks a lot for your support. We will continue to upgrade the app to optimize the users` experience.
Super scientific!

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
Circa Accord now works on your wrist.
APPLE WATCH APP
• Your day's protocol, on your watch. The ring shows how much you've
completed; the card above it shows the one thing to do next, and when.
• Mark a step done with one tap. Taps made away from your phone are
delivered as soon as it's back in range — nothing is lost.
• Talk to your coach. Ask a question out loud and hear the answer read back.
• Log your wake time with a single "I'm awake".
YOUR FULL SLEEP HISTORY
• Circa Accord now reads your complete Apple Health record instead of the
last two weeks. Your trends go back as far as your data does.
• Wake and bedtimes come straight from your Apple Watch's sleep tracking,
so there's nothing to type in. Times you've entered yourself are always
kept — a measurement never overwrites your own answer.
• Your sleep regularity is ready on your first sync, rather than after two
weeks of manual logging.
FIXES AND POLISH
• The app opens on your dashboard instead of asking you to pick your coach
every time.
• Close the app part-way through the assessment and you'll pick up exactly
where you left off.
• Spanish, French and German are now fully translated.
• Your companion appears reliably on a slow connection.
• New users no longer meet an error message on their first analysis. Better watch connection.
