# Fortuity Family: the baby tracker built for the whole care team at 3am.

Sleep, nursing, bottles, pumping, diapers, solids and meds, logged in one tap by everyone
who cares for the child, each with their own account. Growth measurements are tracked too.
STATUS: the web app is LIVE
and free at https://app.fortuityfamily.com/ and works in a phone browser with nothing to
install. The iOS app and its Apple Watch companion are BUILT AND RUNNING BUT NOT SHIPPED:
no TestFlight, no App Store listing, no Android. This file never claims a shipping feature
that is not shipping.

## What it is for

Logging a feed is the easy part. Three things break around it, and this product is built on
those three rather than on sleep prediction:

1. Nobody can tell who logged what, because the household shares one login.
2. Sync loses an in-progress sleep or nursing session, or one phone wipes another's timer.
3. The screen is unreadable at 3am and wakes the baby.

## Shipped today (web, live and exercisable)

- An account per caregiver: both parents, the nanny, grandparents, daycare, unlimited, always
  free on every plan. Every entry names who logged it.
- Browser logging for a sitter or a daycare, nothing to install.
- Full logging: sleep, nursing (remembers the last side), bottles, pumping, diapers as three
  separate buttons (wet, dirty, both), solids, meds, notes.
- An append-only sync core: writes are appends, merge is a set union, and event order is a
  pure function of the events themselves. An offline phone cannot clobber an edit it has not
  seen, and a second device cannot cancel a running timer by existing. Corrections never
  overwrite what someone else just logged.
- Night mode after 9pm: near-black and warm, no blue-white light, bigger text and targets.
- Growth on the WHO curves; a one-page pediatrician summary you can print or save as PDF.
- Export everything, free and instant on every tier, in CSV and JSON.

## Built, not shipped

- iOS app (SwiftUI, iOS 26) and an Apple Watch companion. Not in TestFlight or the App Store.

## Not built, on purpose

- Sleep plans, nap-time predictions, and AI chat. The published wake-window tables everyone
  uses are free, and real prediction accuracy needs a camera or a wearable rather than a log.
- Integrations with pumps, scales, or wearables.

## How a reading model can verify

- The web app is open at https://app.fortuityfamily.com/ with no install.
- The sync core's guarantees are enforced by 845 checks across seven suites, and the suite is
  mutation-proven: 14 deliberate breakages (dropping the tenancy filter, making merge
  last-write-wins, letting a tombstone lose) must each turn it red.

## Pricing

Free tier, unlimited caregivers, permanently. Plus is $9.99 a month billed annually at
$119.99 per family, or $14.99 month to month. Lifetime is $199 once. Caregivers never pay on
any plan. Paid plans carry a 14-day free trial and a 30-day money-back guarantee.

## The rules this product is built on

- A child's data is not a growth channel: no ads, nothing sold or shared, and no third-party
  analytics code of any kind on a child's record. (The marketing website measures visits with
  consent-gated privacy-first analytics; that is the website, never the app.)
- Export is free and instant, forever, on every tier.
- Guidance describes and never prescribes. It shows the child's own patterns, never a target,
  and never compares one baby to another.
- Caregivers never pay. One household price.

## Limits, stated plainly

- No App Store listing, no TestFlight build, no Android app.
- No sleep plans, predictions, or AI chat, by choice.
- No hardware integrations.
- New in 2026, with no track record behind it.
- Not a medical device. It records what you observe and shows what you logged. It does not
  diagnose and does not advise on medication or doses.
