Duckaby
What's inside

Everything Duckaby does, one calm step at a time.

From your due date through the first year, on your phone, with no account.

Pregnancy

Starts at your due date, not at birth.

📋

A due-date plan with 34 dated tasks

Money, admin, health and gear, spread across pregnancy — never a wall of tasks, just the next one. Each state fact (paid leave, postpartum Medicaid, WIC, 529 plans, car-seat law) links to its source, because laws change.

  • Pick your state with one tap — Duckaby can suggest it from your phone's time zone; no location permission is requested.
  • The account-order money guidance plus a 529 projector.

🛒

A buy list that isn't trying to sell you more

22 essentials with safety rules. Mark each one need, registry, bought, gifted, have or skip, track spend, and keep a wish list that links to any store — not just one retailer's own shop.

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 a false low. 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.

Birth & the first 12 weeks

The deadlines that actually have a clock on them.

📅

Deadlines re-anchor to the real birth date

Tap "Baby's here" and after-birth deadlines — the 30-day insurance add, the 30-day FSA/DCFSA life event, the Trump Account (Form 4547), 529 timing, the first pediatric visit, postpartum visits — re-anchor to when your baby actually arrived. Tasks that were already due before you joined show as "catch up", not "overdue".

Baby tracking

Logging that's fast at 3 a.m., and honest about what it knows.

😴

An inspectable nap predictor

The age wake-window prior blended with this baby's own recent windows, recency-weighted, with windows that were followed by a good nap counting more. The first window of the day and windows after a short nap are handled separately. Tap the chip to see why it predicted what it did. An estimate, not a promise — validated on synthetic data only, so far.

📈

Self-scoring, not just self-reported

The Insights tab replays the last 14 days, predicting each sleep from earlier data only, and shows the in-window rate of your baby's personalised model next to the age chart — so you can see whether it's actually working for your baby.

  • Trend flags compare the last 3 days with the prior week: sleep, night wakings, feeds, naps.
  • An AASM total-sleep band for age (no band shown under 4 months, per the consensus).

💬

Ask Duckaby, on your phone

Log or ask in plain words. Everything runs on-device: emergency and crisis phrasing is checked first, and every number in an answer comes from your own log or a cited guideline — it never gives medication doses.

Built for 3 a.m.

A red night mode and one-hand 48 px+ targets. A gap of more than 10 hours since your last log prompts "add missed sleep" instead of guessing a nonsense window from the gap.

A CSV for the pediatrician

Export your baby's log as a CSV to bring to a visit, no account or upload required.

Family & privacy

No account. What leaves your phone is encrypted, and we can't read it.

🔒

Private by design

  • Your log lives on your phone. There is no Duckaby account.
  • Family sharing is end-to-end encrypted: the key lives only in your invite link, and our relay stores data it cannot read.
  • No ads, no analytics or tracking SDKs — on the app or this website.

How the encryption actually works

Coming soon Nursery Listener

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