One tap

Logging that keeps up with a newborn.

The last thing you need at 3am is a fiddly form. Nestlings makes recording a feed, a nappy or an expressing session a single, sleepy tap — and lays the day out as a clear timeline you can actually read.

  • Feeds — bottle, breast and amounts in millilitres
  • Nappies — wet, dirty, and everything in between
  • Expressing sessions, tracked separately

On-device intelligence

Gentle insights, computed privately.

Nestlings uses Apple's on-device Foundation Models to spot patterns and surface gentle, plain-language insights — like whether intake is tracking well for your baby's weight. It all happens on your iPhone. Nothing is sent to a server, because there is no server.

  • Insights generated entirely on-device
  • No API keys, no cloud AI, no data leaving your phone
  • Works even in aeroplane mode

Today's insight

Ada's intake is tracking well for her weight today — around 150 ml/kg across 6 feeds.

Together

Both parents, always in sync.

Share a baby with your partner and every entry appears on both phones the moment it's logged — powered by Apple's own private sync, so you always know who fed the baby last without a single group chat.

  • Instant sharing between parents and carers
  • Home Screen widgets and an Apple Watch app
  • Export your data any time — it's yours

Privacy, seriously

Your baby's data belongs to you.

No beep server

There's no backend collecting your baby's routine. Everything lives on your devices and syncs through your own iCloud account.

On-device AI

Insights run on Apple's Foundation Models, right on your iPhone. Your baby's data is never used to train anyone's model.

You can leave any time

Export everything to a file whenever you want, and delete it all with one tap. No lock-in, no dark patterns.

A gentle note

Nestlings helps you keep track — it isn't medical advice and can't diagnose anything. Its insights are general guidance only. If you're ever worried about your baby's feeding, hydration or health, please contact your maternal & child health nurse, midwife or GP.

A calmer fourth trimester.
