Baby tracker for iPhone

The baby log for both parents.

Log a feed, a nap or a diaper in one tap. Your partner sees it a moment later, with who logged it, so nobody has to ask “when did the baby last eat?” at 3 a.m.

Try free for 7 days. iPhone, iOS 18 or later.

What it does

Less typing at 3 a.m. More sleep for everyone.

Wuzzi does three things and does them quickly, so the log stays complete even on the hard nights.

One tap, then back to the baby

Breastfeed, bottle, diaper and sleep sit right on the Today screen. Tap once to log. Timers keep left and right sides apart and keep running if you lock the phone.

Live timer on the Lock Screen and in the Dynamic Island
Home Screen widget with one-tap buttons
“Log a diaper in Wuzzi” with Siri, or Back Tap
Undo right away if you tapped by mistake

Both parents, one log

Invite your partner, a grandparent or the nanny from the app. Everyone sees the same log, kept in sync through iCloud, and every entry shows who logged it.

No accounts or passwords: it uses the iCloud you already have
“Logged by” on every entry, so handoffs need no recap
Works offline and syncs when you are back online

FAQ

Questions parents ask

Do I need to create an account?

No. Wuzzi uses the iCloud account that is already on your iPhone. There is no sign-up, email or password.

How do two parents share one log?

In Wuzzi, go to More › Share with family › Invite family and send the invitation by Messages or any app. When your partner accepts on their iPhone, you both see the same log, and each entry shows who logged it. Each person needs an iPhone signed in to iCloud.

Can you see my baby’s data?

No. Wuzzi has no server. Your logs are stored on your iPhone and in your own iCloud through Apple’s CloudKit, and are shared only with the people you invite.

Does it work without a signal?

Yes. Everything is saved on your iPhone first and syncs with iCloud when you are back online.

What happens when the free trial ends?

Your plan starts and Apple charges your Apple Account, unless you cancel at least 24 hours before the trial ends. You can cancel any time in Settings › your name › Subscriptions.

Is Wuzzi medical advice?

No. Wuzzi helps you keep track and notice patterns. Insights name their sources, but they don’t replace your pediatrician. If you are worried about your baby, call your pediatrician, or your local emergency number in an emergency.

Which iPhones and languages?

Any iPhone with iOS 18 or later. The app is in English and Spanish.

Can I take my data with me?

Yes. Make a PDF report for any period to share with your pediatrician, or export everything as a CSV file.

Two parents. One log. Fewer questions at 3 a.m.
