Kairos: AI Health Companion

Meet Reed — an AI coach that works from the context you choose to share. Ask about your morning, sleep, energy, or meals. Reed receives a compact iPhone-built summary and is instructed to name the measure and time window behind personal claims, or say when the shared context lacks the answer. Snap a meal photo. Reed estimates visible foods, portions, calories and protein as ranges to review, then asks about the largest uncertainty before you save. WORKS ON IPHONE. DEEPER WITH APPLE WATCH. On iPhone, Kairos can show compatible readings already present in Apple Health after you grant access; when supported data is absent, it offers a clearly labeled sample rather than inventing a live result. Add an Apple Watch and your mornings deepen with overnight recovery, sleep, and a Reserve that reads live while you wear it. Kairos reads these main-sleep-window signals: HRV, sleeping heart rate derived from raw heart-rate samples, sleeping respiratory rate, sleeping wrist temperature, sleep duration, and REM. It gives you one clear verdict for the day: push with intent, hold form, or pull back and recover. Tap your reading to see exactly what moved it — HRV above your norm, more sleep, or a lower sleeping heart rate. Where the engine uses a personal baseline, it is smoothed from sparse, prior-only observations in an up-to-60-day window; sparse or stale signals are left out. BLOODLINE (OPTIONAL). Already have a lab report? Kairos can transcribe legible markers and, where a cited range is available, set each against that range with plain-language context. Doctor questions are built on your iPhone from the visible, medium/high-confidence rows. Bloodline transcribes and educates. It does not diagnose, treat, or prescribe. Uploading is optional and gated by explicit per-upload consent. PRIVATE BY ARCHITECTURE. Kairos computes core health features on your devices. Raw Apple Health samples are not uploaded. Before Reed sends personal data, an in-app permission screen names Amazon Web Services (AWS), the Amazon Bedrock third-party AI service, and the Anthropic Claude model; lists data and purpose; and requires an unchecked permission plus Allow. Not now sends nothing. If allowed, displayed results and the message, memory or meal photo/note you choose are sent. Bloodline asks before every report upload. Processing occurs in United States AWS regions; AWS says it does not share request content with Anthropic. Kairos does not persist readable request or reply content server-side. See the Privacy Policy for retention details. No account to make. No tracking, no ads. Kairos reads from Apple Health and never writes anything back.
