Hear the moment your baby needs you.
A private baby cry monitor for iPhone and Apple Watch — no camera, no cloud, no subscription.

Instant alert + wrist tap
Your iPhone alerts you and your Apple Watch taps your wrist the moment your baby needs you.
Your baby's sounds never leave your phone.
Cry detection runs 100% on-device. Audio is analyzed live on your iPhone and is never recorded, stored, or uploaded — no cloud, no account, no servers. There is nothing to leak and nothing to delete.
Analyzed on the phone
On-device sound recognition does all the work locally.
Never recorded
No files, no clips, no history of sound — only a live read of the moment.
Works offline
No wifi or signal needed. Airplane Mode is fine — it still taps your watch.

Your phone is the monitor
No cameras, no base station, no extra hardware to buy. Your iPhone is all it takes.

Lock Screen & Dynamic Island
A calm, glanceable indicator shows it's actively listening, even with your phone locked.
Sleep History
See each night's sleep duration and a gentle log of cries with timestamps.
Personalized themes

“Are you covered?” checks
Warns you if Do Not Disturb, silenced notifications, or a missing watch app could block an alert.
Make it theirs
Choose a soft rose or sky-blue theme during setup. The accent flows through the listening pulse, status, and alerts — tasteful and nursery-soft, beautiful in light and dark.

Frequently asked questions
Is Little Bird a medical or safety device?
No. Little Bird is a convenience aid that helps you notice when your baby is crying — not a medical device and not a substitute for adult supervision. Always keep your baby within safe reach and follow safe-sleep guidance. Think of it as an extra set of ears, never a replacement for a watchful parent.
Does it need wifi, an account, or the cloud?
No. Little Bird works entirely on your iPhone with no account, no sign-up, and no internet connection required. Cry detection runs on-device, so nothing is ever sent to a server. You can even put the phone in Airplane Mode and it still listens and alerts your Apple Watch.
Does it use a camera?
No. Little Bird is audio only — it never uses your camera and shows no video. It listens for the sound of your baby crying through the iPhone microphone, analyzes it live on the device, and alerts you. There is no footage to store, stream, or worry about being seen by anyone.
Does it work with Apple Watch?
Yes. When Little Bird detects a sustained cry, your Apple Watch taps your wrist instantly and shows a clear alert. A live status screen and a watch face complication let you confirm monitoring is active at a glance, and you can press and hold on the watch to stop listening.
Is there a subscription?
No. Little Bird is a one-time purchase with no subscription, no in-app purchases, and no recurring fees. You pay once and own it. Every feature — Apple Watch alerts, sensitivity tuning, Sleep History, themes, and on-device privacy — is included, with free updates as the app improves.
How much does it cost?
Little Bird is a simple one-time purchase — no subscription, no trial that converts to a fee, and no hidden upgrades. One payment unlocks the complete app on your iPhone and Apple Watch, including all future updates. Check the App Store for current pricing in your region.
Does it keep listening when my phone is locked?
Yes. Once you tap Start Listening, Little Bird keeps detecting in the background even when your iPhone is locked and the screen is off. A Lock Screen and Dynamic Island indicator shows it is actively listening, so you can set the phone by the crib and trust it stays awake.
Does it record or store my baby's sounds?
No. Little Bird analyzes sound live, in the moment, and never records, saves, or uploads any audio. There are no files, no recordings, and nothing leaves your iPhone. The microphone is used only to recognize crying in real time, and that processing happens entirely on your device.
How does it avoid false alarms?
Little Bird waits for a sustained cry rather than reacting to a single short sound, so a cough, hiccup, or passing noise will not trigger an alert. You can tune the sensitivity and set how many seconds of crying must pass before it notifies you, balancing quick alerts with fewer false alarms.
Step away without the worry.
Leave your baby to sleep and go live your evening — Little Bird listens for crying so you don't have to keep checking.
