About
Made for full hands and short nights.
Coo is a baby tracker for breastfeeding, bottles, sleep and diapers that works by events, not stopwatches. Tap "feeding started" once and put the phone down. Coo works out how long the feed lasted from what you log next, so there's no timer to babysit at 3 a.m.
JUST 1 TAP, SERIOUSLY
• Log from a Home Screen widget, the Action Button, or your Apple Watch.
• Say "Log in Coo" to Siri.
• In the app, breast and bottle feeds, sleep and diapers take two taps. Pumping, medicine, tummy time, bath, vaccines and your own custom events take one more.
KNOW BEFORE YOU UNLOCK
Lock Screen widgets show the last feed, how long baby has been awake, and today's totals.
COO FILLS THE GAPS
Baby dozed off mid-feed? Coo ends the feed for you. Forgot "woke up" before a night feed? Coo adds it. Tapped "woke up" twice? Coo keeps the right one. Anything Coo adds looks slightly different, and whatever you log yourself always wins.
FORGOT TO LOG? JUST DRAG IT
Drag an event to the right time, or tap its time and type the exact one. Fixing a time takes 4 taps, and undo is right there.
CATCH UP IN TEN SECONDS
Share one log with a partner, grandparent or nanny through iCloud. Everyone sees the same log and can add to it, and the summary totals everyone's logs for the day. No account, no email, no password.
SEE THE PATTERNS
Press and hold the week view at any hour to see what baby usually does then: "Asleep at 9:05 on 6 of 7 days." Daily summaries total sleep, naps, night wakes, feeds and diapers, with gentle tips for your baby's age.
GROWTH, ON THE CURVES
Weight, length and head size on WHO growth curves, the ones the CDC recommends for babies under 2, with age corrected for babies born early.
THEIR STORY BUILDS ITSELF
Add a batch of photos and Coo places each one on its milestone. Then press play.
YOUR DATA STAYS YOURS
Coo collects no data. Your log lives on your devices and in your own iCloud. Export any week as text or CSV, or bring your log over from another app.
Coo is a logging tool and doesn't give medical advice. Talk to your pediatrician about your baby's health.
