Everything in one calm place
Built for the people raising them together.
Everything the big trackers do — feeds, sleep, diapers, pumping, health, growth and more — in one shared, private log that finally feels calm. All the features, none of the clutter.
The reason it works
Real-time, multi-caregiver sync
Invite your partner, a grandparent, or a nanny to your household. Everyone logs into their own account and sees the same live record. Log a feed on one phone and it appears on the others in a second or two — no refreshing, no shared password, no “did you write it down?”
Both hands full
Just say it. It’s logged.
“Hey Siri, log four ounces of formula in Milk Monster.” Said across a dark nursery — phone still locked, baby still on your shoulder — and the bottle is logged, amount and all, on every caregiver’s phone. Diapers too. No unlocking, no typing. Just say it, and it’s kept.
“Hey Siri, log four ounces of formula in Milk Monster.”
Logged — 4 oz of formula, for Isabella.
One tap
Feeds, sleep, diapers & pumping
Track breastfeeding with left/right sides and duration, bottles split between expressed and formula, sleep sessions, diaper changes, and pumping with per-side totals. The home screen always shows what’s happened today, at a glance.
Live, on every phone
A sleep timer the whole family sees
Tap once when your baby goes down and a live sleep timer starts — running on every caregiver’s phone at the same time. Anyone can tap Wake the moment they stir. No more guessing how long this nap has gone, or whether someone already put them down.

for 16 minutes
Without unlocking
Right from your Lock Screen
Start a feed or pump and a live timer runs on your Lock Screen and in the Dynamic Island — with pause, resume, and stop right there. At 3am, a half-asleep parent never has to find the app. Just glance, and tap.
A gentle nudge
Knows when the next nap is coming
Milk Monster watches the clock so you don’t have to. From your baby’s age and when they last woke, it shows the next nap window opening — a soft heads-up before the overtired tears, right on your home screen. The kind of prediction the big sleep apps charge for, quietly built in.

Peace of mind
Temperature & medicine
Log a temperature reading or a dose of medicine in seconds, with the time recorded automatically. When you’re up at 3am wondering when the last dose was, the answer is right there — and so is every other caregiver.
Their story
Growth & milestones
Record weight, length, and head circumference and see them plotted against WHO growth standards. Keep a gentle journal of milestones — first smile, first roll — with optional photos. Export the whole log as a spreadsheet for your pediatrician anytime.
Without the spreadsheet
Patterns you can actually read
See today’s totals, the last seven days, and day-to-day averages — feeds and pumping broken out by side, bottles broken out by expressed vs formula. The numbers stay calm and readable, in your family’s own words.
Easy on the eyes
Light, dark, or auto
Milk Monster follows your phone’s appearance automatically — or lock it to light or dark, whatever feels right. The dark theme is made for night feeds: calm and gentle at 3am, so a quick glance to log a feed never jolts you awake.
By design
Private by default
No ads. No third-party trackers or analytics SDKs. We never sell or rent your data. Your log is visible only to the caregivers you invite, and you can export or permanently delete everything from inside the app whenever you want.

Reading the charts
Two graphs, no guesswork.
Milk Monster keeps the numbers calm — here’s exactly what each part is telling you.
The growth curve
- The shaded band is the WHO 3rd–97th percentile range — the healthy spread for babies the same age.
- The dashed line is the median, the 50th percentile, for reference.
- Each dot is one of your own measurements, placed by your baby’s age.
- The line at the top translates the latest dot into plain words — “9 lb 8 oz · around the 58th percentile.”
- The tabs switch the same chart between Weight, Length, and Head.
The weekly view
- The tabs switch the chart between Feeds, Bottle, Pumped, Diapers, and Sleep.
- Each bar is one day, Monday through Sunday — today is the dark one on the right.
- The number above a bar is that day’s total, so a quiet day or a growth spurt stands out.
- The header sums the whole week — “60 feeds this week” — to catch a trend at a glance.
- Below the chart, Recent shows the latest entries and which caregiver logged each one.
