Bitty app icon

The whole newborn day, in one app

Feeding, sleep, diapers and growth — one tap each, day or night. Bitty keeps the day together so you don't have to keep it in your head.

Coming soon to the App Store

Built around how the first year actually feels

🍼

A reminder that follows your baby

Not a fixed schedule — the next-feed estimate comes from the average of your last feeds, and moves as your baby does.

🌙

Built for three in the morning

One-tap sleep timer, a day timeline you can actually read, and a dark theme made for night feeds.

📈

Growth read, not just plotted

Weight on WHO percentile curves — plus weekly gain against WHO reference bands and a centile-trend check. Reference information to bring to your paediatrician.

🧷

Everything else, one tap away

Diapers with an age-based daily norm, baths, walks, medicine, mood — and Home Screen widgets so logging never interrupts the day.

Calm by design

Your baby's data is yours

No ads. No analytics. No tracking. No accounts.
Everything you log lives on your device and syncs through your own iCloud — we run no servers and cannot see your data. That's not a policy promise; it's how the app is built.
