A sound diary for the womb

Record their
first heartbeat.

Bring Libbi to every ultrasound. When the doppler whoosh starts, tap record. Then play it back to your baby once they're born — the same heartbeat that lulled them to sleep in utero.

Free to record. Always. No account needed.

Three small moments

From the appointment to bedtime

01

Record at the ultrasound

When the heartbeat comes through the doppler, tap record. Capture it at every appointment — unlimited, free forever.

02

Save it under their name

Trim the quiet bits, add a label, and file it under your baby's profile. A growing diary of the months before they arrived.

03

Play it back to sleep

Layer it with rain, the womb sound, or a lullaby. Let them drift off to the heartbeat they already know by heart.

What's inside

Made for 3am, not for show

Everything you need to keep their first sounds — and help them sleep.

Capture the heartbeat

Record the doppler whoosh at every ultrasound, as many times as you like. Free, forever.

Trim & label

Clean up each clip and name it, so every recording is exactly the moment you want to keep.

Calming sound library

White, pink, brown, rain, ocean, and heartbeat — curated to settle a newborn (and you).

Sleep timer

A gentle fade-out so the sound slips away after they've drifted off — no jarring stop.

Night-sky theme

A soft, dim starfield interface designed for one-handed use during 3am feedings.

Organized by baby

Profiles keep each child's recordings together — a sound diary you'll come back to for years.
