Duckaby
For pregnancy, then baby

From bump to baby, one calm step at a time.

Duckaby starts with your due date: what matters this week, a plan that shows one step at a time, and the facts for your state. When baby arrives, the same app becomes your 3 a.m. log. Your data stays on your phone.

No account. No ads. No trackers — in the app or on this site.

One app, the whole journey

20 weeks to year one

Duckaby grows with you instead of asking you to switch apps at the hospital doors.

  1. ~20 weeks

    Your due-date plan starts: one step at a time, plus sourced facts for your state on leave, Medicaid, WIC and car-seat law.

  2. Birth

    Deadlines re-anchor to your baby's real birth date. The same app becomes your sleep, feed and diaper log.

  3. First 6–12 weeks

    Recovery check-ins and an Edinburgh Postnatal Depression Scale screen, private to your phone unless you turn sharing on.

  4. Year one

    The nap predictor learns your baby's own rhythm and scores its own accuracy as the months go by.

While you're pregnant

Facts for your week, not a wall of tasks

Duckaby Me screen: 33 weeks, baby the size of a pineapple, days to go

Your week, at a glance

Baby's size, days to go and what matters now, from your due date.

Duckaby Plan screen showing the next step

A plan for your due date

Never a wall of tasks — just what's next. Pick your state with one tap (Duckaby can suggest it from your phone's time zone; no location permission) to see sourced facts on paid leave, postpartum Medicaid, WIC, 529 plans and car-seat law. Laws change, so each fact links to its source.

Duckaby glucose screen comparing a Libre sensor with finger-prick meter readings

Libre vs meter, explained

Log finger pricks and import a LibreView CSV. Duckaby learns the usual gap between your sensor and your meter and flags readings that may be false lows. Targets are shown against finger pricks only. It's a notebook, not a diagnosis — your care team decides.

Recovery after birth

Recovery check-ins for the first six weeks, and the Edinburgh Postnatal Depression Scale (a screen, not a diagnosis) with support lines. Your pregnancy and recovery health stays private to your phone unless you turn on sharing.

You, after baby

The same calm one-step-at-a-time plan follows you into the fourth trimester, not just the pregnancy.

Then, baby

The 3 a.m. log, made for one hand

Duckaby catch-up deck: swipe right if a step is done

Swipe, don't type

Catch up in a minute. Right if it's done.

Duckaby Today screen with the next nap window

Knows the next nap

Learns your baby's rhythm from every logged sleep and suggests a next-nap window. An estimate, not a promise.

Duckaby Ask screen answering when the next nap is

Ask anything. Private.

Ask or log in plain words. Answers are worked out on your phone from your own log.

Private by design

Your family's log is nobody else's business

No account, ever

Your log lives on your phone. There's nothing to sign into and nothing of yours on our servers.

End-to-end encrypted sharing

Family sharing is end-to-end encrypted. The key lives only in your invite link; our relay stores scrambled data it cannot read.

No ads, no analytics

No ad networks, no analytics or tracking SDKs in the app. This website has no trackers either.

Nursery Listener Coming soon

A spare phone logs sleep from sound, processed on the device, never stored or sent. It is not a breathing, oxygen or safety monitor.

How we compare

Duckaby vs. the subscription baby trackers

Most baby-tracking apps charge a yearly subscription and phone your logs home. Duckaby doesn't.
