Cocoon: Baby Tracker & Journal

Cocoon is a calm baby tracker that logs the night feed and keeps the memories.

Start a feed or sleep timer, or repeat the last bottle amount with one tap. Log care on this device offline. Sign in when you want to sync with invited caregivers.

LOG IN SECONDS
• Feeds: breastfeeding with left and right timers, bottles and pumping
• Diapers: wet, dirty or both, in one tap
• Sleep: live timers, naps, and nights that run past midnight
• Solids, growth, health and medications, and milestones
• By voice, from a widget, the Lock Screen or Siri

KNOW WHAT'S NEXT
• For babies aged 8 weeks to 12 months, a logged wake can provide an estimated nap window. Estimates adjust as you record more sleep.
• Running timers on the Lock Screen and in the Dynamic Island
• A gentle sleep program you follow night by night, with a check-in each morning

KEEP THE MEMORIES
• A private photo and video journal of everyday moments, with voice notes
• Day, week and month views, daily prompts and "on this day" memories
• Search your journal to find any moment fast

SEE THE PATTERNS
• Sleep, feeding and wake-window trends
• Recorded infant growth; CDC percentiles from ages 2–20, in pounds and ounces or kilograms
• A checkup report to take to your pediatrician
• A milk stash tracker for your freezer supply
• Milestones and gentle, evidence-based guides

SHARED ACROSS THE FAMILY
• Invite a caregiver to sync a shared journal, or send selected moments to grandparents as a separate family update.
• A handoff shows whoever's next on shift the day so far at a glance
• Bring your history from another tracker or journal app, or a CSV file

OPTIONAL AI FEATURES, ONLY WITH YOUR PERMISSION
Ask questions about your own logs, log by voice when your phone can't make out a phrase, photograph a daycare sheet to draft the day's entries, or get a written sleep plan or weekly note. These use Claude, made by Anthropic. Cocoon asks before anything is sent, says what each feature sends, and you can turn them off at any time. Replies are never medical advice.

YOURS TO KEEP
• Export a journal backup with logged events, growth measurements and available photo, video and audio attachments
• Restore that journal backup on another device
• Milk stash, sleep programs and settings are not included in journal backups
