zero@neuralway.aiFrequently asked
Which Apple Watch do I need?
Kairos works on Apple Watch SE and later. The SE gives you a complete, confident reading from four core signals; Series 8 and later add wrist temperature for an even more precise baseline.
Where is my health data stored?
On your device, and nowhere else. Every reading is computed on your iPhone and Apple Watch. There's no account, no cloud sync, and nothing sent to our servers. See our Privacy Policy for the details.
How does the free trial and pricing work?
Kairos is $49/year (about $4.08/month) with a 7-day free trial, or $7/month. You won't be charged during the trial, and you can cancel anytime from your App Store account settings.
How do I cancel my subscription?
Open the Settings app on your iPhone, tap your name, then Subscriptions, select Kairos, and choose Cancel. Your access continues until the end of the current billing period.
Is Kairos a medical device?
No. Kairos is a general-wellness app to help you understand your recovery and train smarter. It does not diagnose, treat, or monitor any condition. Always consult a healthcare professional for medical questions.
My readings look off — what should I check?
Kairos relies on the data your Apple Watch records overnight, so wearing your watch to bed and keeping it charged gives the most accurate read. Baselines also need a few nights of data to settle in. If something still looks wrong, email us and we'll help.
