Alti: Sleep Sounds & Relax - Free Download

Some nights, sleep just won't come. Alti helps you fall asleep faster — with calming sleep sounds, white noise, a gentle night light, and even lullabies recorded in your own voice.
SLEEP SOUNDS AND WHITE NOISE

Choose from relaxing nature sounds — rain sounds, ocean waves, thunder, forest, wind, crackling fire — or steady white noise, pink noise, and fan sounds that block distractions and mask snoring or street noise. Mix several sounds into your own sleep soundtrack, save your favorite combinations, and let the sleep timer fade everything out as you drift into deep sleep.

RECORD YOUR OWN SLEEP SOUNDS

This is what makes Alti different: a personal sleep recorder. Record bedtime stories, sing a lullaby in your own voice, or capture any sound that feels like home — and play it on repeat as you or your baby fall asleep. A familiar voice can calm a restless mind better than any melody. Perfect for kids, for travel, or for keeping a comforting bedtime routine anywhere.

GENTLE NIGHT LIGHT

Turn your phone into a soft night light for your bedroom or nursery. Pick a calming color, dim it to your comfort, and let the timer switch it off automatically once you're asleep. A simple night lamp for adults, kids, and babies alike.

BREATHING BEFORE BED

Wind down with simple breathing exercises that release the tension of the day and quiet racing thoughts. A few slow breaths before bed help you relax, ease anxiety, and prepare your body for rest.
