Fortuity Family

The baby tracker built for the whole care team at 3am.

Sleep, nursing, bottles, pumping, and diapers, logged in one tap by everyone who cares for your baby. Growth tracked too. Each with their own account. Nothing ever lost between phones. Readable in the dark, with one hand.

Start logging, free See how it works

Works in a phone browser today, with nothing to install. The iPhone and Apple Watch apps are built, with TestFlight next.

What actually goes wrong at 3am, and it is never the tracking

Logging a feed is the easy part. What actually breaks is everything around it, and every one below is the kind of complaint parents raise about the apps families already use.

"Did anyone feed her? I can't tell who logged what."One shared household login
"The nursery has no signal and I lost the whole session."Sync that drops in-progress entries
"My phone wiped the sleep timer running on his phone."Last write wins, so someone loses
"The screen blinds me and wakes the baby."Blue-white screen at 3am
"The thing I used last month is behind the paywall now."Basics moving to paid over time
"Our daycare will not install another app."No way in from a browser

Built around the three things that actually go wrong

Everyone gets their own account

Both parents, the nanny, grandparents, daycare. Every entry says who logged it, so "has she been fed?" answers itself instead of turning into a text message. Daycare can log from a browser with nothing to install.

A log you cannot lose

Every tap is saved on your phone before anything else happens, so a nursery with no signal costs you nothing. When two phones reconnect, both sets of entries survive. A running sleep timer on one phone cannot be wiped out by the other.

A screen that respects the dark

After 9pm the app goes near-black and warm, with no blue-white light, bigger text and bigger buttons. Log a feed with one thumb in one tap, no waking anyone up to log a feed.

The moments when everyone needs the same answer

When several people care for one baby, small details pass between tired adults all day. Fortuity Family gives everyone the same record in a phone browser, with nothing to install.

The 3am handoff

You step into the hallway holding a crying baby after broken sleep. Your partner asks when the last bottle finished, and neither of you can quite remember. Instead of guessing or scrolling through old texts, you open the app in your phone browser and see the exact minute of the last feed. The parent taking over can check what happened without making the parent going back to bed give a full report.

Daycare pickup after nine hours

You leave daycare carrying a diaper bag and a tired child. A paper slip is crumpled somewhere in the bag, and a verbal recap is hard to retain while you are getting out the door. You open the web app and see the afternoon bottle time, the exact length of the nap, and the last diaper change. That record tells you the shape of the day before you leave the parking lot.

The nanny’s first week

Your new nanny starts Monday morning. Everyone needs enough information to do the job, but six check-in texts during the afternoon help no one. You both use the same record in your phone browsers. She logs entries as the day moves along, and you can check them from work. You see what has been recorded without interrupting her, and she does not have to retell the day in separate messages.

The three-month checkup

The doctor asks about wet diapers, total sleep over time, and changes in feeding patterns. Those details are hard to reconstruct from memory in an exam room. You open the history view and bring up the record built from daily logs, so the pediatrician has specific information to review rather than estimates assembled on the spot. The app records and describes what happened. It does not diagnose, set targets, or interpret what the patterns mean. That judgment belongs to your pediatrician.

A weekend with grandparents

Grandparents arrive for the weekend ready to help, but they are not going to install software or learn a setup. You send them a link. They open it in a phone browser, check the current routine, and log bottles or naps. Everyone uses the same household record, and nobody has to keep a separate handwritten note or send a recap at every handoff.

The dark bedroom at 2am

You are sitting in a dark room with a baby asleep on your chest, one free hand, screen at minimum brightness. After 9pm the interface goes near-black and warm with no blue-white light, larger text and larger targets. You record the entry with one thumb and put the phone away, without moving through fiddly screens or turning on more light.

Everyone can add to the log without wiping someone else out

Several caregivers record from different phones, and some of those phones are offline when they do it. The engine is built so one person’s entry never overwrites another’s, and so every device computes the same order of events from the same set of records.

Offline entries stay in the record

If you log a diaper change in a basement with no signal while your partner logs a bottle upstairs, both entries survive once your phone reconnects. Writes append to the history instead of replacing it, devices merge their records as a set union, and the order of events is a pure function of the events themselves. Given the same events, every device computes the same sequence.

A disconnected phone cannot replace what it never saw

If a phone stays offline for two hours, the records made on it and the records made elsewhere both survive the reconnect. Append-only entries and deterministic ordering let each device add what it was missing without overwriting what is already there.

One phone cannot cancel another phone’s sleep timer

A sleep timer running on one device cannot be stopped, reset, or canceled from another. The test suite asserts that behavior specifically, including while the other caregiver is recording a separate event.

Corrections do not erase new entries

If you fix a feeding time while your partner records a nap, your correction does not remove the nap. Edits and deletions use explicit tombstones, and a deletion beats later modifications to that record without touching adjacent records someone else created.

Seven suites, 845 automated checks

The tests assert that merging is commutative, associative, and idempotent, that event ordering forms a total order identical on every device, and that the JavaScript and Swift engines produce byte-for-byte identical output. The web app runs this tested logic today. The native clients are built and are not distributed.

The tests have been tested

Fourteen deliberate breakages were introduced, including removing the tenancy filter, changing merges to last-write-wins, and letting a tombstone lose. Every one turned the suite red. That does not prove the software has no defects. It does show that a green suite is not green because the checks do nothing.

The same suite checks contrast and medical language

It asserts that every text and background pair clears Web Content Accessibility Guidelines (WCAG) AA across all three appearances (day, dusk, and night), and that no user-facing copy carries a medical claim. The app records and describes a history. It does not diagnose or advise.

Households stay separated

Automated tests assert that every sharing surface renders exactly one child, and the server is tested against records crossing between households. Logs for different children do not mix on one screen.

None of this is visible when it works, which is the point. It is listed here because the alternative, an app that silently drops the bottle someone logged in a basement, is not something a parent can detect either.

One tap means one tap

Wet, dirty, and both are three separate buttons. Nursing remembers which side was last. A sleep you forgot to start can be fixed after the fact in two taps, and correcting an entry never overwrites what someone else just logged.

Against Huckleberry

Huckleberry says more than five million families use its products, and it is genuinely good. It is bigger than us, it does more than us, and it wins four of the rows below. What follows is the comparison as it actually stands, with every Huckleberry figure read off their own pages on 26 July 2026.

Sources. Huckleberry's prices and its "over 5 million families" claim were read on 26 July 2026 from huckleberrycare.com/pricing and huckleberrycare.com. Rows marked "not described" or "not offered as a named feature" mean exactly that: the capability is absent from their own published pages, not that we tested and it failed. The other large trackers (Baby Tracker, Baby Daybook, Glow Baby) publish no price on the web at all and sell through in-app purchase, so they are deliberately not priced here rather than guessed at. Prices change: check the linked page before deciding anything on this table.

What you get, and what we will not do

A child's record is not a growth channel. These are rules the product is built on, not settings that could quietly change.

One boundary stated precisely, because it is the kind of line that gets blurred: this marketing page measures visits with privacy-first analytics, and only after you accept the banner. That is this page. The app and your child's record carry no third-party analytics code of any kind, and there is no setting that turns any on. The full privacy notice.

Our commitments to your family, on the way in and the way out

The test of a product holding a family’s record is what happens on the way out. Here is that answer, in full, before you start.

Export everything, free

Your full care history comes out as CSV and JSON, instantly, on every tier including the free one. It is never a paid feature and never an upsell, and it does not shrink or lock if you cancel. Keep the files, read them, or take them somewhere else.

Every caregiver is free, on every plan

Unlimited caregiver accounts at no charge on every plan. Both parents, the nanny, the grandparents, and daycare each hold their own account, so adding another person never pushes you onto a paid tier and never creates a per-seat fee.

No third-party analytics on a child’s record

The app carrying your child’s daily record has no third-party analytics code of any kind, and there is no setting that turns any on. This marketing website measures visits with consent-gated, privacy-first analytics. That is this website, never the app.

No ads, nothing sold or shared

No advertising, no selling your information, no sharing a child’s record with data brokers or marketing networks. Feeding logs, sleep patterns and the rest of a household’s routine are not a growth channel, and the business does not depend on turning them into one.

It shows the patterns and stops there

The pattern views describe what is in your child’s own record. They do not set benchmarks, prescribe targets, compare your child with other babies, or tell you what to do next. The app shows what was logged and how it changed. What it means is a conversation for your pediatrician.

Canceling takes one tap

Paid plans carry a 14-day free trial and a 30-day money-back guarantee, and canceling takes one tap. If you cancel, export stays available, your records do not become a paid add-on, and the size of your household never creates a new charge.

One price for the household

Questions

Is there an iPhone app?

The one you open is the web app, and it works in any phone browser with nothing to install, which is also how a nanny or a daycare logs. The Apple iPhone operating system (iOS) app and its Apple Watch companion are built and running behind it.

Does the nanny or grandparent have to pay?

No, and that is a rule rather than a promotion. Every caregiver gets their own account on the free side of every line, on every plan, with no limit on how many. One household pays at most once.

What happens if two phones log at the same time with no signal?

Both sets of entries survive. Writes are appends rather than overwrites, merge is a set union, and the order of events is computed from the events themselves, so an offline phone cannot clobber an edit it has not seen and a second device cannot cancel a running sleep timer just by existing.

Can I get my data out?

Yes, free and instant, forever, in CSV and JSON, on every tier including the free one. Export is never an upsell and never behind a paywall.

Do you sell or share my child's data?

Your child's record is shared only with the caregivers you authorize. There are no advertisements, nothing is sold or shared with data brokers or marketing networks, and there is no third-party analytics code of any kind on a child's record. The marketing website measures visits with privacy-first analytics, and only after you accept; that is the website, never the app.

Will it tell me whether my baby is sleeping enough?

It shows your child's own patterns and never a target to hit, and it never compares your baby to other babies. It records what you observe and shows what you logged. It does not diagnose, does not advise on medication, and is not a medical device.

How is this different from Huckleberry?

Huckleberry is bigger and does more: over five million families, expert-designed sleep plans, SweetSpot nap predictions, an AI chat, and apps in both stores. Fortuity Family is built on the three things a tired parent actually trips over: a separate account for every caregiver so every entry says who logged it, sync that cannot lose an in-progress session, and a screen legible at 3am. The full comparison.

Is anything being charged today?

The free tier is live and free. Paid plans carry a 14-day free trial and a 30-day money-back guarantee, and canceling takes one tap.

What it is for

Worth knowing before 3am.

The record only exists from the day you start keeping it.

Parents, grandparents, nannies, and daycare staff can each have their own free account, permanently. When each person records feeds, naps, and diapers, everyone sees the same history instead of guessing what happened three hours ago or passing around notes. Fortuity Family works offline, then reconciles when devices reconnect.

It runs in your phone’s browser, with nothing to install and no device enrollment. Your data stays yours, with instant exports whenever you want them. Start your record on the free tier, or try Plus free for 14 days to see whether one shared history makes coordination easier across the household.
