Baby Mantra is a calm, simple baby sleep app for iPhone. It plays steady sleep sounds, softly spoken affirmations and your own recorded voice, together or on their own, so the last minutes of the day feel the same every night. Below is a full tour of the features, how it works in three steps, and exactly what is free. If you are still weighing your options, our fair comparison of the best baby sleep apps is a good place to start.

What Baby Mantra does
Most sleep sound apps stop at sounds. Baby Mantra adds two things that set it apart: 84 spoken affirmations written for babies, kids and parents, and your own voice, mixed right into the soundscape.
| Feature | What you get |
|---|---|
| Sleep sounds | 27 sounds: white, pink and brown noise, rain, ocean, womb and heartbeat, household hums and gentle music |
| Mixing | Play up to 3 sounds at once, each with its own volume |
| Spoken affirmations | 84 short, warm phrases in 7 themes, layered softly over your sounds |
| Collections & playlists | Ready-made mixes and affirmation playlists, from First Night to Parent’s Peace |
| Your voice | Record lullabies or messages. Recordings stay on your phone |
| Sleep timer | 15 minutes to 2 hours with a gentle fade-out, or play all night |
| Night mode | A dim screen that stays awake, for feeds and settling |
| Controls | Lock-screen controls, bedtime reminders, favorites and saved mixes |
| Privacy | Works offline, no account, no ads, no tracking |
27 soothing sounds, mixed your way
The sound library covers five families: noise colors (white, pink, brown), nature (rain, rain on roof, thunder, ocean waves, waterfall, wind, forest birds, crickets, fireplace), womb and comfort (womb sounds, heartbeat, shushing, purring cat), household hums (hair dryer, vacuum, fan, washing machine, train) and music (music box, soft piano, harp, acoustic guitar, singing bowl, kalimba). Hear previews and read what each is best for in our guide to baby sleep sounds.
Blend up to three at once, for example white noise with gentle rain, and set each one’s volume separately. That way you can keep the overall level soft while still getting the texture your baby settles to.
84 spoken affirmations in 7 themes
Affirmations are short, loving phrases like “You are so loved” and “Rest now, little one,” spoken in a calm voice. The 7 themes are Love & Security, Identity & Worth, Strength & Growth, Belonging, Calm & Peace, Gratitude, and For Parents. When an affirmation plays, your sounds dip gently, then rise again. We think of them as a bonding ritual and a peaceful end to the day, not a treatment. Explore every theme in bedtime affirmations.

Collections and playlists
Not sure where to start? Collections pair sounds that work well together, and playlists group affirmations by mood: First Night, Sweet Dreams, Wrapped in Love, You Belong Here, Little Brave Heart, Just As You Are, Grateful Hearts, Moonlit Lullaby, Ocean Embrace, Golden Hour, Gentle Courage and Parent’s Peace. First Night is free.
Your own voice
Your voice is the sound your baby knows best. Record yourself singing a lullaby or saying goodnight, or ask a grandparent to record a message, then play it inside a mix. Recordings are stored only on your phone and are never uploaded. See how in record your own lullaby.
A timer that fades out, or all night
Choose 15 minutes to 2 hours. When the time is up, the sound fades out slowly over about 30 seconds instead of stopping abruptly. Prefer continuous sound? Choose All night and control playback from the lock screen.
How Baby Mantra works in 3 steps
- Pick a sound or a collection. Start with one steady sound, or tap a collection like First Night. Add up to two more sounds and balance the volumes.
- Add affirmations or your voice. Choose an affirmation playlist, or add your own recording. Your sounds dip softly while the words play.
- Set the timer and dim the screen. Pick 15 minutes to 2 hours, or all night. Turn on night mode, put the phone across the room, and let the evening wind down.
Built for safe, calm nights
A sleep app should make safe sleep easier, not harder. That shaped how Baby Mantra works:
- Per-sound volume makes it easy to keep the total level low, around 50 dB or softer at your baby’s ear. That is the limit recommended for hospital nurseries, which every infant sleep machine in one study exceeded at maximum volume close to the crib (Hugh et al., 2014).
- The fade-out timer means sound doesn’t have to play all night if you’d rather it didn’t.
- Dim night mode keeps the screen low so you can check the time during a feed without a bright light.
- Offline play means no ads and no buffering in the middle of the night.
