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, from your iPhone or your Apple Watch.
In the middle of the night you don't want a busy dashboard. Vivi's Today screen answers the three questions you have, in the order you have them.
"Sleeping for 12 minutes." "Feeding on the left for 4 minutes." Running timers are big and easy to see.
"Nap at about 2:20, in 25 minutes." Sleepy Time learns your baby's rhythm and estimates the next nap or bedtime.
"Fed 1 h 20 m ago, left side." "Diaper 2 h ago, wet." The time since each thing is always one line away.
Turn on only what you need. Each activity has its own soft color, so you can read the day at a glance.
Breast with left and right timers, bottles of breast milk or formula, combo feeds and solids with reactions.
Naps and nights with a timer, or add a sleep after the fact. Day and night split by your baby's night hours.
Wet, dirty or dry in one tap, with color, texture, rash and blowout when you need them.
Time each side on its own or both at once, and log amounts per side or in total.
Weight, length and head size on WHO growth charts, plus the CDC's milestone checklist.
Temperatures, medications and doses, symptoms and vaccines, all in one place.
A map of the 20 baby teeth, with when each one was first noticed and fully in.
First smile, first laugh, first steps. Vivi adds the age automatically.
A few words and a photo about your day, signed by whoever wrote it.
Bath, tummy time, story time, or anything else you want to keep an eye on.
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. They can stop it from their phone when the baby wakes up, and the nap is saved on every device.
Vivi uses what you log to make estimates and notes. It doesn't act like your doctor.
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.
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 and does not diagnose. No AI, nothing leaves your phone.
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.
Start sleep, time a breastfeed and switch sides, log a bottle with the Digital Crown or a diaper in one tap.
Running timers and the next-nap countdown live on the Lock Screen and in the Dynamic Island.
"Since last feed, sleep and diaper" on the Home Screen, and a sleep timer button you can tap without opening the app.
"Baby is asleep in Vivi Baby." "When was the last feed in Vivi Baby?" Log it with your hands full.
A native iPhone and Apple Watch app, written for Apple devices.
Most baby trackers keep your child's feeds, sleep, health notes and photos on the company's servers, behind an account. Vivi doesn't need one. 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.
Read the privacy policyVivi imports CSV exports from Nara Baby, Huckleberry and Baby Tracker, 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.
Nara Baby isn't free anymore: it costs $9.99 a month, or $99.99 for life, after a 7-day trial. If you don't pay, you can still see and export your data, but you can't log anything new. Everything you tracked for your baby in Nara is free in Vivi: feeds, pumping, diapers, sleep, growth, milestones and health. And you can bring your Nara history with you. Here's how to export from Nara and switch.
Huckleberry's free tier covers the basics, but its Apple Watch app, widgets and nap predictions need Plus, which is $68.99 a year. In Vivi, the Watch app and widgets are free. See what each Huckleberry plan costs, or export your Huckleberry data and bring it over.
Baby Tracker by Nighp lists CSV export as a paid feature. Here's how to export your log and import it into Vivi.
Now. Vivi Baby is on the App Store for iPhone, with a companion app for Apple Watch. It is free to download, and logging is free. Vivi Plus is optional, adds Sleepy Time, Insights and Checkups, and comes with a 14-day free trial.
No account needed. There is 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.
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.
Usually not. Vivi Plus supports Apple Family Sharing, so one subscription covers everyone in your Apple Family Sharing group, such as your partner, at no extra cost. Someone outside that group, such as a nanny with their own Apple Account, can still log everything for free and needs their own subscription only for Vivi Plus features.
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.
In your iCloud Drive, as ordinary Markdown and YAML text files plus photos. If iCloud Drive is off, the same files stay on your iPhone only. 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.
Yes. Vivi imports the CSV exports from Nara Baby, Huckleberry and Baby Tracker (by Nighp), 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.
Yes. In Nara, tap your child's avatar and choose Export Data. Then in Vivi, open Preferences and choose Import from Nara Baby. Nara now costs $9.99 a month or $99.99 lifetime after its 7-day trial, but without a plan it still lets you view and export, so you can move your history either way. Logging in Vivi is free.
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.
No. Vivi shows patterns in what you log and does not diagnose. For anything that worries you, talk to your child's doctor. Checkups are there to make that conversation easier, with a summary of the weeks since the last visit and a list of your questions.
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.
An iPhone running iOS 18 or later. iCloud Drive is needed only to sync your log across devices and to share it with other caregivers. Without it, Vivi keeps the log on that iPhone. The Apple Watch app needs watchOS 26 or later. There is no iPad or Android version.
