The baby tracker you share with your partner, live.
Your baby's story, logged with love.
Bunavi turns breastfeeding, bottles, pumping, diapers and naps into one-tap logs — then blooms into wake-window schedules, WHO growth charts and a milestone journal you share with your partner, live.
Free to download · No ads · Privacy
Feeding, sleep, diaper and growth tracking in one app
Built for one-handed, half-asleep logging — because you have a baby in the other arm.
Breast, bottle, pump or solids — one tap and done
Start a left- or right-side breastfeeding timer mid-yawn, log a bottle in millilitres or ounces, track pumping totals, and keep a solids diary once purées begin.
- Left/right timers that remember where you left off
- Bottle amounts, pumping sessions and daily totals
- A little confetti every time you log — you earned it


Naps and nights, gently timed
One tap starts the sleep timer; Bunavi learns your baby's rhythm and suggests age-based wake windows, so you catch the sleepy cues before the overtired tears.
- Wake-window guidance that grows with your baby
- Day naps and night sleep on one gentle timeline
- A cozy plum night theme for 3 a.m. feeds
Watch them bloom on WHO growth charts
Log weight, length and head circumference and see your infant bloom along WHO percentile bands — beautiful curves you'll actually understand at a glance.
- Weight, length & head circumference percentiles
- A growing sprout that blooms with every entry
- Ready to show at every pediatrician visit
For context only — always chat with your pediatrician.


Celebrate every first
First smile, first roll, first step — Bunavi keeps a milestone timeline with badges and gentle age-based suggestions, so no first slips by unnoticed.
- A storybook timeline from day one
- Badges and streaks that make logging a tiny joy
- Gentle age-based suggestions — tap when it happens

How Bunavi works
Add your baby — or twins — in under a minute. Name, birthday, done.
Feeds, naps, diapers and firsts — each one a single tap, even one-handed at 3 a.m.
Wake windows, growth curves and milestones bloom from your logs — shared live with your partner.
Loved by our first families
The 3 a.m. logging is so fast I do it half-asleep. The wake-window hints gave us our evenings back.
We both log, we both see everything. No more "when did she last eat?" texts from the other room.
Two babies, one app. The twin switcher alone is worth it — and the growth charts are gorgeous.
