HRV & sleep readiness, private
Each morning, your body tells a story. Kairos reads it - and shows you why.
While you slept, your heart-rate variability, resting heart rate, breathing, and temperature were all quietly recording how well you recovered. Kairos pulls those signals from Apple Health, compares them against your own personal baseline, and gives you one clear verdict for the day: push with intent, hold form, or pull back and recover.
No charts to decode at 6am. No 50-metric dashboard. One honest read on whether today is yours.
AND, UNLIKE THE REST, IT SHOWS YOU WHY.
Tap your reading to see exactly what moved it - HRV above your norm, deeper sleep, a lower resting heart rate — each signal measured against your own 60-day baseline, warm when you're above it, cool when you're below.
PRIVATE BY DESIGN.
No account to make. No cloud sync of your health. No tracking, no ads. Kairos reads from Apple Health on your iPhone and Apple Watch and never writes anything back. And a report you read with Bloodline is encrypted, transcribed once, never stored, and kept privately on your iPhone.
BUILT FOR YOUR WRIST.
Kairos needs an Apple Watch. Wear it to sleep, and your reading is waiting each morning, on your iPhone and on your wrist.
WHAT YOU GET
• A single morning readiness verdict, in plain language
• The "why"- every signal vs. your personal baseline
• A glance-able reading on your Apple Watch
• Months of private, on-device trends
BLOODLINE (OPTIONAL).
Already have a lab report? Kairos can transcribe your markers and set each against a cited optimal range, with plain-language context and questions to bring to your doctor. Bloodline transcribes and educates. It does not diagnose, treat, or prescribe. Uploading is optional, and with your explicit per-upload consent it sends only the report images to an AI service for transcription; nothing from the report is stored.
