Coming soon for iPhone & Apple Watch

The baby tracker that stays calm at 3 a.m.

Log a feed, a nap or a diaper in one tap, see when the next nap is likely, and share it all with everyone who cares for your baby. Vivi Baby keeps your log in your own iCloud Drive, so it stays yours.

  • Feeds, sleep, diapers and pumping in a tap
  • Timers shared live with your partner
  • No account, no ads, no tracking
Made for tired parents

Three answers, one glance

In the middle of the night you don't want a busy dashboard. Vivi's Today screen answers the three questions you actually have, in the order you have them.

What's happening now?

"Sleeping for 12 minutes." "Feeding on the left for 4 minutes." Running timers are big and impossible to miss.

What comes next?

"Nap at about 2:20, in 25 minutes." Sleepy Time learns your baby's rhythm and estimates the next nap or bedtime.

What happened recently?

"Fed 1 h 20 m ago, left side." "Diaper 2 h ago, wet." The time since each thing is always one line away.

Track what matters to you

Everything your baby does in a day

Turn on only what you need. Each activity has its own soft color, so you can read the day at a glance.

Feeds

Breast with left and right timers, bottles of breast milk or formula, combo feeds and solids with reactions.

Sleep

Naps and nights with a timer, or add a sleep after the fact. Day and night split by your baby's night hours.

Diapers

Wet, dirty or dry in one tap, with color, texture, rash and blowout when you need them.

Pumping

Time each side on its own or both at once, and log amounts per side or in total.

Growth & milestones

Weight, length and head size on WHO growth charts, plus the CDC's milestone checklist.

Health

Temperatures, medications and doses, symptoms and vaccines, all in one place.

Teeth

A map of the 20 baby teeth, with when each one was first noticed and fully in.

Firsts

First smile, first laugh, first steps. Vivi adds the age automatically.

Journal

A few words and a photo about your day, signed by whoever wrote it.

Routines

Bath, tummy time, story time, or anything else you want to keep an eye on.

Caring together

One baby, two parents, zero "did you feed her?"

Invite your partner, a grandparent or the nanny. Everyone logs from their own iPhone, and every entry shows who saved it.

Start a nap timer on your Apple Watch and it appears on your partner's phone and Lock Screen right away. They can stop it from their phone when the baby wakes up, and the nap is saved on every device.

  • Each caregiver uses their own Apple Account
  • Timers keep counting even if the app closes or the phone restarts
  • Log offline, and it syncs when you're back
A little help thinking ahead

Less guessing, more napping

Vivi turns what you log into something useful, without pretending to be your doctor.

Sleepy Time

An estimate of when your baby will be ready for the next nap or bedtime. It starts from typical wake windows for your baby's age, then follows your baby's own pattern after about five days of logged sleep.

"Why this time?" explains every estimate. Watch for sleepy cues too.

Insights

Gentle notes when a pattern shows up in your log, like "Bedtime is getting later" or "Feeds are closer together", with a link to the guidance it's based on from the WHO, CDC, AAP and others.

Vivi shows patterns, not diagnoses. No AI, nothing leaves your phone.

Checkups

Before a pediatrician visit, Vivi sums up sleep, feeds, diapers, growth, fevers, vaccines and new teeth since the last one. Keep your questions in a list and jot down the answers.

No more trying to remember how many wet diapers there were on Tuesday.

Built for iPhone, the native way

Log from wherever your hands are free

Apple Watch

Start sleep, time a breastfeed and switch sides, log a bottle with the Digital Crown or a diaper in one tap.

Live Activities

Running timers and the next-nap countdown live on the Lock Screen and in the Dynamic Island.

Widgets

"Since last feed, sleep and diaper" on the Home Screen, and a sleep timer button you can tap without opening the app.

Siri & Shortcuts

"Baby is asleep in Vivi Baby." "When was the last feed in Vivi Baby?" Hands full, still logged.

Your family's data

Your baby's log lives in your iCloud Drive. Not on our servers.

Most baby trackers keep your child's feeds, sleep, health notes and photos on the company's servers, behind an account. Vivi doesn't. Every entry is a small text file in a "Vivi Baby" folder in your own iCloud Drive, shared only with the people you invite.

That also means your records don't depend on us. You can open them in the Files app or any text editor, and they'll still be readable in twenty years, when your baby wants to know when they took their first steps.

Read the privacy policy
  • No account, no sign-upVivi uses your Apple Account. We never learn your name or email.
  • Plain files you ownMarkdown and YAML text, plus photos with location data removed.

Switching is easy

Bring your baby's history with you

Vivi imports CSV exports from Nara Baby and Huckleberry, shows you a preview, and won't create duplicates if you import again later. And if you ever leave, export everything to CSV whenever you like.

Questions parents ask

When can I download Vivi Baby?

Vivi Baby is being tested by families on TestFlight right now and is coming to the App Store for iPhone and Apple Watch. Leave your email at the bottom of this page and we'll send you one message on launch day.

Do I need to create an account?

No. There is no Vivi account, no password and no sign-up. Vivi uses the Apple Account already on your iPhone and stores your baby's log in your own iCloud Drive.

Can my partner and I both log from our own phones?

Yes. A family is a shared folder in iCloud Drive. Invite your partner, a grandparent or a nanny and each person logs from their own iPhone with their own Apple Account. Every entry shows who saved it, and a timer started on one phone shows up on the others right away.

Does it work on Apple Watch?

Yes. From your wrist you can start and stop sleep, time a breastfeed and switch sides, run the pump timer, log a bottle with the Digital Crown, and log a wet, dirty or dry diaper in one tap.

Where is my baby's data stored?

In your iCloud Drive, as ordinary Markdown and YAML text files plus photos. You can open them in the Files app or any text editor. Vivi has no server that stores your log. The only thing it sends out is anonymous timer state, so a running timer can appear on your partner's Lock Screen in a second or two.

Can I switch from another baby tracker?

Yes. Vivi imports the CSV exports from Nara Baby and Huckleberry, with a preview before anything is saved. Importing the same file again later won't create duplicates. You can also export your own history to CSV at any time.

Does Vivi use AI?

No. Sleepy Time and Insights are simple, predictable rules that run on your iPhone. Insights link to their sources, such as the WHO, CDC and American Academy of Pediatrics, so you can read the guidance yourself.

Is Vivi medical advice?

No. Vivi shows patterns in what you log, not diagnoses. For anything that worries you, talk to your child's doctor. The Checkups feature exists to make that conversation easier, with a summary of the weeks since the last visit and a list of your questions.

Does it work for twins or several children?

Yes. You can track several children in one family, switch between them in a tap, and run timers for each. Babies born early can use their due date for age-based guidance such as Sleepy Time and milestones.

Which devices does it need?

An iPhone running iOS 27 or later with iCloud Drive turned on. The Apple Watch app needs watchOS 26 or later. There is no iPad or Android version.
