PumBaby is a baby tracking app for parents who are truly sleep-deprived.

I created this app because I understand that feeling: the baby just cried, I have one hand holding the baby, while the doctor asks, "How many times did the baby eat yesterday, and how long did they sleep?" — I searched through Zalo, Notes, and notes… couldn't find anything. PumBaby gathers everything in one place, allowing you to record in under 2 seconds, without having to open each cluttered screen.

What problem does the app solve?

Parents need to know when the baby last ate, how long they slept, whether the diaper is wet or dirty, if they have a fever, and if they have taken medicine — but there’s no time to input data. PumBaby is designed for that moment: one-handed, in the dark, while the baby is fussing.

What can you do with PumBaby?

Quick recording, no need to “open the app and find the menu”

• Wet diaper, dirty diaper, mixed diaper — just a tap and it's done
• Bottle feeding: record ml/oz, type of milk (breast milk, formula, water…)
• Breastfeeding: set separate timers for left/right, remember which side was just fed for next time
• Nap, night sleep: start a timer, if the app closes and opens again, it continues running
• Breast pumping, tummy time, temperature, medication, vaccinations, weight/height, developmental milestones — 11 tracking types in one app

Main screen — instantly recognizable

• How long ago was the last feeding
• Most recent diaper
• Which timer is running
• Pin the most used items to the home screen

Timeline & statistics

• View the whole day of the baby by color, easy to read
• Sleep and feeding charts — smooth, not like an Excel spreadsheet
• Growth chart compared to WHO standards (Premium version)

Usable at night

• Dedicated Night mode: warm, dim, non-blinding — record at 3 AM without “flashing” the whole room

Your data is yours

• No registration required to start
• Data is saved on the device first, normal offline usage
• Export CSV for doctor visits, or JSON for complete backup
• Premium: iCloud backup (iOS), share snapshots for spouse/grandparents to import on their devices

Free vs Premium

Free (sufficient for long-term use):

• 1 baby profile
• All 11 tracking items + timer
• Dashboard, timeline, 7-day statistics
• Light/dark/night mode interface
• Export CSV & JSON

Premium (for larger families or deeper needs):

• Multiple baby profiles (twins, siblings)
• Main screen widget — quick recording without opening the app
• 30-day statistics, deeper sleep & feeding analysis
• WHO growth chart
• iCloud backup, family sharing, app icon customization

The core journal feature is free forever — I don’t want parents to pay just to record the baby's midnight feeding.

Who should try it?

• New parents, in the “living on short naps” phase
• Parents who work, needing quick sync with caregivers
• Grandparents babysitting, wanting an app in Vietnamese, with large text, easy to tap
• Anyone who has spent 10 minutes looking for “last time the baby ate” before a doctor’s appointment

A little about me

I developed PumBaby because I found many baby tracking apps either too complicated, forced cloud registration, or had interfaces like hospital software — when at 3 AM, you just need a button to press and peace of mind.
