Tumbly: Baby & Newborn Tracker

Tumbly is the calm baby tracker built for the first hard years — for parents who want every feed, diaper, sleep, and pump in one place without learning a new app at 3am.

Tap, type, or just say it. Tumbly uses Apple Intelligence on your iPhone to turn "five ounce bottle" into a saved entry — no typing, no menus, no blinding the room with full screen brightness.

ONE-HANDED LOGGING
• Feeds — bottle or breast, side, duration, ounces, formula or breast milk
• Diapers — wet, dirty, both, dry
• Sleep — start, end, and a Live Activity timer on your lock screen
• Pumping — duration, ounces, side
• Growth — weight, length, head circumference, charted over time
• Doctor visits — questions you asked, what the pediatrician said

VOICE LOG
Tap the mic and say what happened. Apple's on-device speech recognition transcribes the audio without sending anything to a server. "Four ounce formula bottle" becomes a log entry. "When did she last poop?" reads back the answer from your own data.

PEDIATRICIAN BRIEF
One tap turns the past two weeks into a one-page PDF — daily averages, charts, your visit notes, and a plain-English summary. Walk into every appointment prepared.

PATTERNS & INSIGHTS
Find the rhythm your baby actually has — typical feeding intervals, longest sleep stretches, side preferences, peak hours. All computed on your iPhone.

SCHEDULE PREDICTIONS
Tumbly learns when feeds tend to land and shows you what's likely next, so the rest of your day doesn't catch you off-guard.

SHARE WITH YOUR CO-PARENT
Real-time CloudKit sharing. Invite a partner, grandparent, or nanny over iMessage — both phones stay in sync without an account, password, or third-party server.

WIDGETS & LOCK SCREEN
Home Screen widget for one-tap logging. Live Activities surface running timers right on the lock screen.
