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.
