Track tiny
moments.
A baby tracker that works when you can barely keep your eyes open. One hand. One tap. Done.

It's 3am. You're not alone.
Your baby just finished eating. You need to log it before you forget — because your pediatrician will ask, and you won't remember which feeding was which by morning.
Every baby tracker on the market either looks like a medical device or requires six taps to log a bottle. You're holding a baby in one arm and your phone in the other.
You don't have six taps in you.
Everything you need, nothing you don't.
The core loop: tap the floating button, pick the event, done. You're back to staring at your beautiful, screaming child.
Feedings
Breast, bottle, or solids. When, how much, how long.
Sleep
Start/stop a live timer, or log after the fact when you forgot to hit start.
Diapers
Type, color, consistency. Yes, you will care about poop color.
Vaccinations
Pre-loaded schedules for the US, UK, and Vietnam. Knows what's due.
Growth
Weight, length, head circumference plotted against WHO percentile curves.
Milestones
Rolling over, first words, crawling. Based on WHO and CDC data.
Appointments
With file attachments and reminder emails so you stop missing them.
Works offline.
Log events without wifi. Everything syncs when you're back online. Because babies don't care about your signal strength.
Scheduled dark mode.
The app automatically dims at bedtime — 7pm by default, configurable. No more getting flashbanged by a white screen during night feeds.
Caregiver sharing.
Invite grandparents, your partner, or a nanny. Everyone sees the same data. No more "did you feed her?" texts.
PDF reports.
Walk into your pediatrician's office with a formatted summary of the last 30 days — feedings, sleep patterns, growth charts, vaccination status. All generated with one tap.
Analytics that observe, never judge.
"Average feeding gap this week: 2.5 hours" — not "You should be feeding every 2 hours!" henrii shows you patterns. You decide what to do with them.

Why "henrii"?
henrii is named after the developer's son, Henry.
The double-ii is the logo — two figures standing side by side. One a little bigger than the other. Parent and baby.
Built for 3am.
