Your Kairos

Kairos is the personal analytics engine for everything you'd otherwise spread across seven apps and a spreadsheet. One timeline, your data, your patterns — surfaced, never prescribed.

MORNING RATING
Each morning the home page asks you to rate yesterday across three axes — energy, mood, focus — on a 1–5 scale. Your ratings become first-class features in the analyzer: modes get characterized in your own vocabulary, and coupling can answer "what tracks with mood?" against every other series you're collecting.

HEALTH
Connect Apple Health on your iPhone. Sleep, HRV, recovery, workouts, and steps flow into one timeline. Compatible with WHOOP, Oura, Garmin, Fitbit, and Apple Watch — all write into HealthKit; Kairos reads from there. Strava, Peloton, Zwift, and Nike Run Club workouts route the same way — enable each app's Apple Health export.

MONEY
Plaid integration imports transactions and balances across banks, brokerages, and credit cards. Auto-categorized via 15 curated tags. Recurring subscriptions auto-detected from your transactions — track them before they pile up.

CALENDAR
Sync up to five Google Calendars side-by-side. Meeting load, free-time breakdown, and category mix across 30d / 90d / 1y windows. A weekly rhythm heatmap surfaces when your time actually gets booked vs. when it stays free.

SOCIAL
Family, Friends, and Partner each get their own view. Track who you haven't reached out to in months, ranked by relationship depth. The Partner view goes deepest — a lifetime 7×24 message-rhythm heatmap, 52 weeks of volume, streak counters, and since-first-contact totals.

iPHONE
Connect your encrypted iPhone backup from a Mac. Messages, calls, and photos become heatmaps, time-of-day histograms, and top-contact rankings.

ANALYTICS
A per-user Hidden Markov Model identifies stable patterns in your data — "modes" you cycle through, change-points when something shifts, couplings between metrics. Your morning rating becomes a feature in the model, so modes get characterized in your own words instead of system-inferred meaning. Descriptive, never prescriptive.

PROSE
An optional narrative layer that reads what the analyzer surfaces and describes it in plain language. A 7-day recap, a rotating pair of your own past messages with the context of the day around them, and a branching Discover view that lets you explore any pattern the analyzer flagged. Uses Claude; strictly opt-in; nothing goes to an LLM unless you turn it on.

PRIVATE BY DEFAULT
Per-user encryption for stored OAuth tokens. Export your full database any time. No ads. No user-tracking analytics. No data sold or shared, ever. Error monitoring via Sentry with PII scrubbed before submission; CAPTCHA on signup via Cloudflare Turnstile.

BUILT FOR
You, if you've tried Notion, Airtable, bullet-journaling, and three different habit trackers and wanted a single home that actually understands time as the primary axis — and treats your own labels as the ground truth, not someone else's.

Email verification and optional TOTP 2FA.
