Baton: Baby Tracker

Baton is a calm baby log for the night shift. Big buttons at the bottom of the screen, a dim night mode, and one log that both parents share.

LOG IN ONE TAP
• Breastfeeding timer that switches sides and remembers which side is next
• Bottles (breast milk, formula or mixed), pumping, solids, sleep, diapers, growth and notes
• On iPhone, pause, switch or stop a feed from the Lock Screen and Dynamic Island (Live Activity)
• Home Screen and Lock Screen widgets

SHARE THE NIGHT SHIFT
• Invite your partner with a link: they see and add entries on their own iPhone or iPad
• Grandparents and caregivers can follow along with view-only access
• Sync goes through your own iCloud. No account, no Baton server

GROWTH ON THE WHO CHARTS
• Weight, length and head circumference with their WHO percentile (birth to 5 years), e.g. "P62 · within the usual range", on the WHO curves
• Neutral wording and the source named: never a diagnosis

VACCINES AND REMINDERS
• The Vietnamese national schedule (TCMR, Circular 52/2025/TT-BYT), or any vaccine with your clinic's dates
• A reminder the evening before each dose

HEALTH LOG AND BEFORE THE BIRTH
• Medicines, temperatures and symptoms, with the last dose on Today so no one gives it twice. No dose advice
• Expecting? A contraction timer until the birth

MOMENTS, A PHOTO DIARY
• The little firsts: a note, up to four photos, a date and a milestone (first smile, first tooth, first steps…)
• Each monthly birthday, a Month card with that month's photos, growth and milestones to share
• The CDC milestone checklists from 2 months to 5 years, in neutral words

SLEEP SOUNDS AND LULLABIES
• White, pink and brown noise, rain, ocean, fan, shush, heartbeat and three lullabies, made on your iPhone, with a gentle fade-out timer
• White noise is free for 15 minutes at a time

MILK STASH
• Log bags in the fridge or freezer and see which to use first, with dates from published storage guidance

SIRI AND A MORNING SUMMARY
• “Log a bottle in Baton”: feeds, diapers and sleep by voice; Control Center buttons (iOS 18)
• Last night next to the 7-day average, with what your partner logged

SEE THE DAY AND THE WEEK
• Today's timeline and totals, 7-day charts, a weekly summary, full history, CSV export
• iPad: a sidebar, two columns and keyboard shortcuts; Discover shows every feature

FREE, AND STAYS FREE
Logging, timers, widgets, partner sync, full history, 7-day charts, CSV export, vaccine schedules and reminders, the WHO percentile of the latest measurement, 20 moments and share cards are free forever. We promise not to move them behind a paywall later.

BATON PLUS (OPTIONAL)
• The usual next-nap window for your baby's age, from published wake-window tables, plus a reminder before it
• 30- and 90-day trends
• A PDF report for your pediatrician
• More children (twins are always free) and your own reminders
• The full WHO growth chart with every measurement, and unlimited moments
• Every sleep sound and lullaby, longer sleep timers and all night
Baton Plus is $9.99 a year with a 1-week free trial, or $19.99 once. Both include Family Sharing. Prices may vary by country.

The yearly subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID at confirmation of purchase (after the free trial, if you start one). Manage or cancel it in your Apple ID settings. Your partner does not need to buy anything.

Baton shows published reference ranges (WHO growth standards, CDC milestones, milk storage guidance, wake-window tables, the national vaccine schedule) and suggestions, not medical advice. Ask your pediatrician about your baby's health.

No ads. No account. Your baby’s logs are never sent to us. Names, notes and entries are end-to-end encrypted in iCloud.
