About
Baby cried… Lulai heard it and started the lullaby.
Lulai uses on-device artificial intelligence to detect crying in real time and automatically plays the sound you selected. No account is required. Open the app, start listening, and leave the rest of the night to Lulai.
WHY LULAI? • Cry detection runs on your device; audio is not uploaded to a server • The selected sound starts automatically when crying is detected • Night mode: a dark, simple interface • The lock screen shows listening status and the track that is playing • Audio keeps playing while the app is in the background
Free includes cry detection, the classic lullaby, night mode, sound check, and a 30-minute auto-stop. Pro features are open for the first 7 days. You are not charged when that period ends.

FEATURED
Smart cry detection Analyzes room audio with on-device artificial intelligence and starts a soothing sound when crying is detected. The sensitive setting can also trigger on quieter crying.
Your voice With Pro, record a lullaby, a shush, or a short message. That recording can play when crying is detected.
Soothing lullabies and sounds The classic lullaby is free. Pro unlocks the calm lullaby, piano, white noise, rain, and ocean.
Add your own sounds With Pro, import a favorite lullaby or song from Files.
Sound order With Pro, the tracks you pick play in sequence, at the interval you set, while crying continues. Drag the list to rearrange it.
Background playback Audio keeps playing while the app is in the background.
Night mode A dark, simple interface for a dark room.
Privacy Detection and recordings stay on the device. Audio is not uploaded to an external server.
Lulai Pro is a one-time purchase and does not auto-renew. Pro includes every lullaby and nature sound, your voice recording, your own music, listening times other than 30 minutes, automatic lullaby switching, and reordering.
Note: Lulai is not a medical device. It is a sleep and soothing aid for parents.
