## What is Kairos?

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.

## Version history (last 5 releases)

### 1.2.1 — 2026-09-09

Reed now keeps meal context current when you add or remove food, and handles interrupted requests more reliably. Meal scans recover more consistently after an upgrade or restore. Find “Redeem offer or coupon code” on the plans screen or in Settings → Membership. This update also improves membership status, large-text layouts, chart labels and Sleep navigation.

### 1.2.0 — 2026-09-01

Meet Reed — an AI coach that works from the context you choose to share.
• Ask about your morning, sleep, energy, or meals. Reed answers from your own
  summary and is instructed to name the metric and time window it uses.
• Snap a meal photo; review honest calorie and protein ranges before saving it.
• New plan: Kairos Complete — with Reed. Existing Kairos plans keep their
  current price.
• Works from compatible Health context on iPhone. Deeper with Apple Watch.
Everything you share with Reed is permission-first. The new disclosure names
AWS, Amazon Bedrock and the Anthropic Claude model, lists what is sent, and
requires an unchecked permission plus Allow. Raw HealthKit samples remain
on-device; current processing and retention details are in the Privacy Policy.

### 1.1.2 — 2026-08-12

A new Kairos, and your nights in focus.

• Redesigned throughout. Every screen now reads against one line: your own normal. Your numbers sit above or below it, so you see where you stand before you read a word.

• Sleep positions, drawn properly. Back, front, left, and right, each with its own illustration, the time you spent there, and the turns between them.

• Turns you can trust. A recording fault meant some nights were set aside instead of read. Fixed, and checked against how people actually move in their sleep.

• Your longest hold. The stretch you stayed in one position, uninterrupted.

• Arc. Ninety days of your readiness, with your personal range drawn behind it.

• Honest empty states. When Kairos cannot see something, it says so and tells you why, instead of showing a zero.

• Moment now breathes with you, with gentle haptics so you can close your eyes.

### 1.1.1 — 2026-07-20

Polish and privacy.

• Your sleep positions now appear as soon as your watch's recording arrives, without waiting on Health to finish syncing.
• A steadier morning: your reading holds until last night has synced instead of guessing without it.
• Clearer guidance when Kairos needs access to your health data, or when it's time to set up sleep tracking on your watch.
• Your overnight motion data and daily check-ins stay strictly on your devices.
• Stability and clarity improvements across Sleep, Today, and Body.

### 1.1.0 — 2026-07-18

Your nights, in full.

• New Sleep tab. Your night now has its own home: how you slept, when you woke, and your body's rhythm, told simply.
• Sleep positions. Wear your watch to bed and Kairos maps how you slept: back, front, left, right, with how long you spent in each and how often you turned.
• Awakenings. See the moments your night broke, and whether they clustered.
• Reserve, tuned to you. Kairos now occasionally asks how your reserve felt and quietly adjusts to your body's answers.
• Live stress. Your at-rest signal, reachable from Today and Body, always.
• A calmer, cleaner design across every screen.
