The baby tracker that's fastest at 3am

Log feeds, sleep, and diapers in a tap or two. Sway keeps the rhythm so you don't have to — calm, no-pressure, never a report card.

Two taps at 3am

Log a feed before you're fully awake

The things you reach for at night — feed, sleep, diaper, and which side — are one tap from the home screen, then a confirm. No menus, no forms, no hunting.

  • The four core logs, one tap each
  • Backdate in seconds — "she fell asleep 40 min ago"
  • Every log is undoable from the toast
  • Big targets, one-handed, bottom of the screen

Never lose a timer

Timers that survive a handoff

Start a nursing or sleep timer and it lives on the server, not your phone. Hand the baby to your partner and the timer is still ticking on their screen. The last-feed chip always remembers which side.

  • Breast timer with a left / right toggle
  • Last side remembered — the other side pre-selected
  • A crashed phone or a handoff can't lose it
  • A gentle nudge if a timer runs impossibly long

The pediatrician screenshot

See the whole day at a glance

History is a clean timeline by day, plus a rhythm grid: two weeks of sleep, feeds, and diapers as colored bands. It's the view parents screenshot for the doctor — export it as an image or PDF.

  • Reverse-chron timeline with per-day totals
  • 24-hour × 14-day rhythm grid
  • Who logged what — "Logged by Sam"
  • Export for the pediatrician in one tap

Guidance, not just logging

Your baby's own rhythm, learned

Sway reads the patterns in your own log — typical time between feeds, how wake windows are stretching, the longest night stretch — and guesses the next nap window. Always a guess from your baby's week, never a norm to measure up to.

  • Next nap-window guess from recent wake stretches
  • Feed-interval and sleep trends over time
  • Longest-stretch and cluster-feed detection
  • Descriptive and warm — never a percentile grade

The long view

Growth curves and every first

Plot weight, length, and head on the WHO curves — your baby's own line, corrected for prematurity when you set a due date. Capture the firsts — smile, roll, tooth, step — with a photo, never framed as a race.

  • WHO 0–24 month percentile curves
  • Corrected age for preemies, automatically
  • Firsts library + custom milestones with photos
  • Printable pediatrician visit summary

The 3am companion

Ask about your baby, from your baby's data

Sway's AI companion knows your log — today's feeds, last night's sleep, the growth curve — and answers in plain language. It explains patterns; it never diagnoses.

  • Answers from your own baby's data
  • Log by chat; capture tasks by voice, hands-free
  • A warm weekly rhythm digest
  • Always names its limits and points to your pediatrician

Hands-free

Say it, and it's on the list

Hands full with a baby? Tap the mic and talk. Sway turns what you say into tasks, checks them off, and reads the list back — no typing at 3am. Feeds, sleeps and diapers are logged by tap or by chat.

Both parents, one log

Invite a partner — they see it instantly

Share the baby with your partner, a grandparent, or a nanny. Everyone logs into the same record, and it syncs the moment anyone taps. No more "did you feed her?" texts — you can just look.

The Rest Of It

The admin a baby generates, out of your head

Check-ups to book, the birth to register, the box of 3–6 clothes waiting in the loft. Put it here in one line and stop carrying it. Today stays short, everything else waits quietly in Ready — and Routines sits alongside for the small daily things.

  • Capture anything in one line — or just tell Sway
  • Today stays short; the rest waits without shouting
  • Routines for vitamin drops, tummy time, the steriliser
  • No streaks to break, no overdue red

Today

Routines

Small touches, big difference

The little things that make tracking at 3am survivable.

Last-side memory

The most-praised small feature in the category — you never have to remember which side.

Ends well, not with nagging

Looks like diaper season is winding down

When a log goes quiet for weeks, Sway offers to tuck it away instead of reminding you. Growth and milestones stay as the keepsake.
