Dandini: Baby Sleep Sounds

One tap, and the room goes quiet.

Dandini is a white noise app built around the 3am moment: a tired parent, one hand free, a baby who needs to go back to sleep. Pick a sound, set a timer, put the phone down. Everything else stays out of the way.

SOUNDS THAT SETTLE A BABY
• White noise, pink noise and brown noise
• Gentle rain on a tin roof
• Ocean waves, slow and rolling
• Heartbeat, just like the womb
• Womb sounds, muffled and deep
• Shush — a parent's rhythmic shhh
• Hair dryer and box fan
• "Dandini dandini dastana" — a Turkish lullaby, hummed softly

Every sound loops with a soft crossfade, so your baby never hears the gap. All of them ship inside the app: no streaming, no buffering, no internet needed.

WAKES UP WHEN YOUR BABY DOES
Turn on cry detection and Dandini listens while the sound is off. When it hears the pattern of a cry, your bedtime sound starts playing within seconds — often before your baby is fully awake.

Audio is analysed on your phone. Nothing is recorded, nothing is uploaded, nothing leaves the device.

NOTHING SOOTHES LIKE YOUR VOICE
Record a lullaby, a hum or a long shhh — 5 to 60 seconds — give it a name, and Dandini plays it on repeat alongside the other sounds, looping with the same soft crossfade.

A SLEEP TIMER THAT FADES
15 minutes, 30, 45, an hour, two hours, or all night. Instead of cutting out and startling your baby, the sound fades down gently before it stops.

BUILT FOR ONE HAND, IN THE DARK
• Lock the screen so little hands can't change anything
• Dim the screen while playing, to keep the room dark
• Volume limit that caps output at a nursery-safe level
• Dark and OLED-friendly by default
• Plays in the background, with controls on the lock screen and in the notification shade
• Optionally starts your bedtime sound the moment the app opens

PRIVACY AND SAFETY
No account. No ads. No tracking. The microphone is used only for cry detection, only while you have it switched on, and only on your phone. For safe listening, keep the device 3–7 feet (1–2 m) away from the crib.

Available in English and Turkish.

For newborns, naps, colic evenings, teething nights, travel, car seats — and for anyone who just needs the room to be quiet.

Sleep well, little one.
