PulseOSC: Heart Rate in VRChat
Heart Rate to OSC Receiver
£1.99
iPhone Duo & iOS 27 ready! Track HR & active energy via Apple Watch, AirPods Pro 3/Powerbeats Pro 2 or Bluetooth HR devices. Headphones/Bluetooth require iOS 26+.
PulseOSC seamlessly bridges your Apple Watch, compatible headphones (AirPods Pro 3, Powerbeats Pro 2), or third-party Bluetooth devices health data with your OSC-compatible applications (like VRChat or Resonite). Whether you want to drive avatar animations with your heart rate or display it in the chatbox, PulseOSC makes it simple and reliable.
Real-Time Heart Rate: Streams your live heart rate from Apple Watch, compatible headphones (AirPods Pro 3, Powerbeats Pro 2), or third-party Bluetooth devices to your device via OSC.
VRChat Ready: Native support for Avatar Parameters (drive animations/effects) and the VRChat Chatbox (display BPM text).
Fully Customizable: Configure target IP, Port, and specific OSC addresses to fit your unique setup.
Visual Feedback: A beautiful, modern interface that lets you monitor connection status and data flow at a glance.
Privacy First: Your data stays under your control. PulseOSC only transmits health data directly to the local IP or domain you specify—no external cloud servers involved.
*This application is not authorized, endorsed, or supported by VRChat Inc. or Yellow Dog Man Studios S.r.o. Only the heart rate data it sends via the OSC protocol can be retrieved by the VRChat or Resonite clients. Beyond this technical interaction, there is no affiliation between them.
more - Added Live Activities: view heart rate, optional active energy, and workout pause status on the Lock Screen and Dynamic Island on supported devices.
- Preview VRChat Chatbox text or OSC avatar parameters in Live Activities. You can toggle Live Activities and their previews in Settings.
- Added support for iPhone Duo and iOS 27 and improved the main screen, Settings, and Statistics layouts for wider screens and window resizing.
- System requirements: to support iPhone Duo and iOS 27, PulseOSC now uses Xcode 27, which no longer supports building for watchOS 8. As a result, this version requires watchOS 9 or later on Apple Watch. iPhone and iPad still support iOS/iPadOS 16 or later; Live Activities require iOS/iPadOS 16.2 or later.
