About this app

It's 3am. You're wondering, "Is this normal? Did the baby eat enough? Has it been too long since the last feed?"

You don't need another notebook that just records numbers. You need something that reads your logs back to you and tells you what to do next.

That's the difference. This app doesn't just track feeding, sleep, diapers, growth, meds, milestones and vaccines. It interprets them, turning every log into a live daily plan and timely, age-aware guidance grounded in WHO, AAP and CDC standards. Less guessing at 3am. More calm, informed decisions between pediatrician visits.

A DAILY PLAN, NOT JUST A LOG
Get a clear schedule for feeds, naps and bedtime, built from your baby's real pattern and gently guided toward a healthy, age-right rhythm. It updates live as the day unfolds, so you always know what's next.

LOG EVERYTHING IN ONE TAP, EVEN ONE-HANDED
Feeds (breast, bottle, solids), sleep, diapers, medicine, growth, milestones and vaccines, all tracked in seconds. Fast enough for a sleepy 3am session with a baby in your other arm.

UNDERSTAND YOUR DATA, DON'T JUST COLLECT IT
Hundreds of age-aware tips powered by your own logs plus WHO, AAP and CDC guidelines. Wonder Weeks leap detection and cross-category signals surface things you might miss, like "last fed 3h ago, your usual interval is 2h 30m." These are helpful patterns, not medical diagnoses, made to help you notice things early and talk to your doctor sooner.

SLEEP BETTER AS A FAMILY
A dedicated sleep dashboard with wake windows, nap tracking, overtired-window alerts and weekly trend charts, so you can spot the rhythm instead of fighting it.

SEE GROWTH IN CONTEXT
WHO, AAP and CDC percentile curves plus a clothing-size forecast that estimates when the current size will stop fitting. Forecasts are pattern-based estimates, not certainties, but they help you plan ahead.

NEVER MISS A SHOT OR A MILESTONE
A full WHO vaccination calendar with reminders, plus CDC and WHO developmental milestones tracked by age. Milestone nudges flag what's due by age to keep you on schedule. Schedules vary by country and provider, so always confirm with your clinic.

KEEP EVERYONE IN SYNC
Invite your partner, grandparents or nanny so each person logs from their own phone into one shared, real-time timeline. Caring for twins or more? Track multiple babies with ease.

WORKS ANYWHERE, RESPECTS YOUR DATA
Offline-first, so it saves to your device first and works without signal. No ads, no third-party trackers, no data sold. One-tap CSV and JSON export, 30-day recovery for deleted items, and account deletion anytime.

MADE FOR
New and expecting parents, and the caregivers around them, from newborn through the toddler years, especially first-time and data-curious parents who want age-appropriate, guideline-based reassurance between checkups.

This app supports your parenting; it does not replace your pediatrician. Free to try, with an optional subscription unlocking the full experience.
