About this app

An app used next to a sleeping baby should stay quiet.
Dad's Heart never interrupts playback with an ad. No server, no account, no internet needed.

■ Your own voice
Record 5 seconds of your "shhh", your calm breathing, or a soft hum.
The womb filter softens the high frequencies so it sounds like it did from inside mom's belly.
Recordings stay on this phone and are never uploaded.

■ Three layers at once
Blend white noise, a lullaby and dad's voice, each with its own volume.
· 12 sounds — heartbeat, inside the womb, brown/pink/white noise, rain, ocean waves, fan, stream, campfire, car ride, vacuum
· 4 lullabies — Brahms' Lullaby, Twinkle Twinkle Little Star, Frere Jacques, Silent Night (music-box tone)

■ Volume always starts at zero
Even if your phone's media volume is maxed out, nothing blasts next to your baby.
Every launch, every sound change: back to zero. Press play with confidence.

■ Sleep timer
15 minutes, 30 minutes, 1 hour or all night, with a gentle 8-second fade before it stops.

■ Cry detection
After playback stops, if your baby stirs, the phone quietly fades your mix back in.
It only measures loudness and discards it immediately. Nothing is recorded or sent.

■ Built for 3 a.m.
A pure black screen and one big play button. One tap is all a sleep-deprived parent should need.

■ Sounds with no copyright strings attached
Every sound is synthesized by the app itself. No audio files are downloaded.
All lullabies are public domain melodies.

■ Privacy
· Recordings and settings never leave your device
· No account, no analytics of your audio
· Fully functional in airplane mode

If you'd like to support development, tap "Cheer up, Dad ☕" and watch a short ad.
You never have to — nearly everything works without it.

Sleep well tonight.
