Built for forty weeks — and the years after.
Cudly isn't a heartbeat recorder with extras bolted on. It's a complete pregnancy companion — built around the daily reality of being pregnant, not the marketing fantasy.
Heartbeat & sound
Capture the soundtrack of pregnancy through your phone alone.
Phone-microphone heartbeat capture
Passive amplification of the low-frequency sounds inside your bump. Works best from week 16+.

Save every session with date, week, and your own note. Build a sound library across pregnancy.
Shareable audio clips
Send a 30-second recording to dad, grandma, or your group chat — privately.
BPM estimation
When the signal is clear, Cudly estimates beats per minute. (Not a medical reading.)
Voice memos to baby
Record short messages your baby will hear back one day. Date-stamped forever.
