Sonarly vs HeartBeatSync

The first sound your baby ever heard was your heartbeat. For nine months, your heartbeat was your baby's whole world: a steady, constant rhythm they knew before they knew anything else. Sonarly brings that comfort back. Rest your fingertip on your phone's camera for a few seconds, and Sonarly captures the gentle rhythm of your pulse. It then weaves that rhythm into a warm, personalized soundscape (ocean, rain, forest, or night) tuned to you. Not a generic loop. Yours. Why your heartbeat? Newborns are soothed by what's familiar, and nothing is more familiar than the rhythm they grew up listening to from the inside. Sonarly takes that idea and turns it into sound your baby can drift off to, carried on the one phone you always have with you. Made for real nights with a newborn • Personalized to you - your own pulse shapes the soundscape, so it's never just white noise • Four ambient worlds - ocean, rain, forest, and night • A sleep timer, so the sound fades when it's no longer needed • Keeps playing while your phone is locked, through the whole drift-off • Calm, gentle audio with no sudden sounds or jarring transitions • Always with you - no extra device to buy, charge, or pack A companion, not a replacement Love your sound machine? Keep it. Sonarly is the personal, portable layer. The one that's tuned to you and always in your pocket, whether you're at home, visiting family, or out for the day. Sonarly is a comfort and relaxation aid. It is not a medical device and is not intended to diagnose, monitor, or treat any condition. Quiet the night. Let your heartbeat carry them home.
