Sleepling
Soft sounds for sleepy little ones.
Sleepling helps your baby settle and drift off with soft, steady sounds. It's simple enough to use one-handed, in the dark, with a little one in your arms. Turn on listening and it starts soothing on its own when your baby stirs. It works completely offline.
Nine soothing sounds
- Shush: a rhythmic "shhh… shhh…", or record your own so your baby hears your voice
- Heartbeat: a calm resting heartbeat over a soft womb whoosh
- White, pink and brown noise: from bright and airy to deep and rumbly
- Fan: the steady airflow so many babies love
- Rain: gentle, steady and never the same twice
- Ocean: calm waves on a beach, recorded from just up the sand
- Lullaby: Brahms' Lullaby on a music box
Made for nighttime
- One tap to play, another to pause

- Listening: starts soothing when your baby fusses, then fades out and listens again
- Keeps playing with the screen locked or the silent switch on
- Play, pause and switch sounds from the Lock Screen
- A dark, dim design that won't light up the nursery
- No accounts, no ads, no tracking, and no data collected
Questions and answers
Does Sleepling keep playing when my phone locks?
Yes. Sound keeps playing with the screen locked and with the silent switch on. You can pause it or switch sounds from the Lock Screen or Control Center.
How does the sleep timer work?
Tap Timer and choose 15, 30 or 45 minutes, or 1 or 2 hours. The sound fades out gently over the final minute, then stops. Choose Off to play until you stop it.
The sound stopped during a phone call. Is that normal?
Yes. iOS pauses other sound during calls and alarms. Sleepling resumes on its own when the call ends. If your headphones or Bluetooth speaker disconnect, Sleepling pauses so the sound doesn't suddenly come from your phone.
How loud should it be?
Quiet. Keep your phone at least 2 m (7 ft) from your baby's crib, with the volume no louder than a soft shower. Sleepling is not a medical device. If you're worried about your baby's sleep, talk to your pediatrician.
Can Sleepling start on its own when my baby wakes?
Yes. Tap Listen and turn on Start when baby stirs. When Sleepling hears fussing or crying, it plays your chosen sound for 5 to 30 minutes, fades out and listens again. If your baby is still fussing, it starts again right away. It works with the screen off; keep your iPhone plugged in overnight. Choose Low sensitivity if it starts for other sounds, or High to catch soft whimpers.
Does Sleepling record my baby?
No. When listening is on, the microphone only measures how loud the room is, on your iPhone. Nothing is recorded, saved or sent anywhere.
Does Sleepling need an internet connection?
No. Everything runs on your iPhone, so Sleepling works offline, in airplane mode and anywhere you travel.
