HeartSync Mobile sends your live heart rate from iPhone and Apple Watch to HeartSync, the VST3/AU plugin. Shape tempo, effects and sound with your heartbeat, live in your DAW. You need both: HeartSync Mobile on your iPhone and the HeartSync plugin in your DAW. USE THE HEART-RATE GEAR YOU ALREADY HAVE • Apple Watch: open HeartSync on your watch, or start from your iPhone, for real-time heart rate. • Bluetooth heart-rate devices: chest straps, arm bands and watches that broadcast heart rate over Bluetooth, such as Polar, Wahoo, Garmin and COROS. HeartSync remembers your device and reconnects on its own. • Apple Health as a fallback. Updates can be delayed, depending on how often your device syncs. LIVE AND RELIABLE • Real-time streaming over Bluetooth, about once per second. • Keeps streaming while your iPhone is locked. • See your BPM live on the iPhone dial and on your wrist. SIMPLE AND PRIVATE • No account and no sign-up. • Heart rate goes over Bluetooth to HeartSync on your own Mac. • Optional analytics, off by default. Streaming works either way, and no heart-rate readings are ever included. WHAT YOU NEED • iPhone with iOS 16.4 or later • HeartSync plugin (free, VST3/AU) running in your DAW on a Device with Bluetooth • A heart-rate source: Apple Watch, a Bluetooth heart-rate device, or Apple Health HeartSync is a creative and biofeedback tool, not a medical device.
