Help & FAQ
Answers to the most common questions. Still stuck? We're one email away.
Is Kairo medical advice?
No. Kairo estimates your circadian timing to suggest better scheduling. It is not a medical device and does not diagnose, treat or prevent any condition. If you have a sleep or health concern, talk to a clinician.
Where does my health data go?
Nowhere you don't control. Raw sleep, heart-rate and HRV are read from Apple Health and processed on your iPhone. They are never uploaded, and the cloud is never in the loop for a recommendation.
Do I need an Apple Watch or an Oura / Whoop?
No. Kairo works from your sleep timing and a short chronotype questionnaire. It gets sharper if you connect Apple Health or a wearable, but none is required.
Will Kairo change my calendar?
Never on its own. It reads free/busy to propose a plan, and only writes a block after you confirm with a tap. It never moves events you already have.
What does Kairo cost?
Kairo is free to start, with an optional Pro subscription that unlocks advanced features. You can plan your day with the core app without paying.
Which devices are supported?
iPhone on iOS 17 and later. Android support is on the roadmap.

Not medical advice. Kairo estimates circadian timing; it does not diagnose or treat sleep disorders.
