Coo Baby Tracker: Newborn Log

Who fed her last? When did he go down for his nap? Coo answers that in one glance, for both parents.

No account. No subscription required. Coo collects no data at all: your baby's log lives in your own iCloud and nowhere else.

TRACK EVERYTHING, FAST
• Sleep: start a nap with one tap, live timer, nap vs night automatically
• Feeding: breastfeeding by side, bottle (breast milk or formula, oz or ml), solids with allergen tracking
• Diapers: wet, dirty, texture and color
• Pumping: sessions and volume
• Medicine: vitamins and medications with dosage and quick presets
• Growth: weight and height on WHO percentile charts
• Milestones: CDC checklist by age
