About this app

Your baby grows so fast, and the days blur into one. Esti helps you keep every little thing — from night feeds to first milestones — and see your baby's own rhythm behind it all.

Log everything in seconds:
• Feeding — breastfeeding, bottle, solids and pumping, with a timer at hand
• Sleep, diapers, walks and baths
• Health — temperature, medicine, illness, vaccinations and doctor visits
• Growth — weight, height and head circumference
• Moods, milestones and photos to remember

Understand, don't just track:
• Your baby's daily rhythm of sleep and feeding at a glance
• Sleep, feeding and diaper trends over a week, a month or three
• Growth on WHO percentile charts, with a full measurement history
• Reminders to feed on time, give medicine and never miss a check-up
• A one-page summary for a doctor's visit — growth, sleep and feeding, with what changed

Esti is always there — an assistant you can simply talk to. Ask her anything about your baby, and she answers from your own records:
• "How did he sleep this week?", "When is the next nap likely?"
• Send a photo — a rash, a diaper or a formula label — and ask what it is
• Don't feel like typing? Just say it out loud, in any language
• Log a feed, a nap or a temperature in one sentence — Esti prepares a card, you just confirm
• She predicts the next sleep window from your baby's rhythm and flags when a regression begins
Esti supports you too — with breastfeeding, recovery and the hard days. She's caring but no replacement for a doctor: for anything worrying, she gently suggests seeing a professional.

Made to be by your side:
• Multiple babies in one account
• Metric or imperial units
• Light and dark themes, 9 languages
• Export your data to CSV or PDF
• Search your whole diary — including the notes you wrote on an entry
• Invite your partner and track together, always in sync
• Private and secure: your data stays with you, synced across all your devices
• Sleep sounds for settling and for the night — eight looping sounds, white noise among them, with a timer that fades out instead of cutting

Esti Premium unlocks the assistant, the sleep-window prediction, the doctor's report and the sleep sounds.

Less guessing, more cuddles. Download Esti and enjoy the little moments.

Esti is an app for tracking and information only; it does not provide medical advice.

What’s new

• Sleep sounds (Premium): eight looping sounds, from waterfall to heartbeat, that keep playing with the screen off and fade out on a timer
• The doctor's report is now offered on the appointment itself, covering the last three months
• It works for families who track only vaccinations, weighings and illnesses
• Reminder options that could never arrive are no longer offered
• The journal opens showing everything again, and its filter counts are real
