About LubDub - Heart Sound Recoder
LubDub empowers individuals to take a proactive approach to a better lifestyle. Using your iPhone’s built-in microphone, the app captures heart sounds (phonocardiograms) and applies smart filtering to highlight the “lub-dub” rhythm of your heartbeat. If you are simply curious about your cardiac rhythm, LubDub makes it easy to record, listen, and reflect on your heart sounds — right from your chest, without any extra devices.
