One-tap logging

Start a feed or sleep with a single tap. Timers keep running even if you lock the phone, and nursing remembers the last side โ€” built for one-handed 3am logging.

Free nap predictions

Your SweetSpot shows the next good nap window from your baby's age and rhythm โ€” computed on your device, no account, and free forever.

WHO growth charts

Plot weight, length, and head against official WHO percentile curves, calculated privately on your iPhone.

Both parents in sync

Invite a co-parent or nanny and everyone logs to the same baby. Syncs privately through iCloud โ€” no Nestling account, no servers.

On your wrist

Log a feed, nap, or diaper from Apple Watch while you hold the baby. It all syncs back to your iPhone.

Private by design

Your family's data lives on your device and your own private iCloud. No account, no data selling โ€” ever.
