Live heart-rate bridge
Turn your Apple Watch into a Bluetooth heart-rate strap.
MyHRM rebroadcasts your live Apple Watch heart rate as a standard Bluetooth sensor. Garmin Edge head units and Peloton equipment can use your Watch — no chest strap.
Heart rate is relayed live — never stored or sent to a server.

How it works
Apple Watch heart rate on your head unit in three steps
Start a Watch workout
Open MyHRM on Apple Watch and start heart-rate broadcast. HealthKit begins a workout session so BPM updates keep flowing.
Tap Start Broadcasting
On iPhone, tap Start Broadcasting. Your iPhone begins advertising as a Bluetooth heart-rate sensor named “MyHRM”.
Add MyHRM on your device
On your Garmin Edge (Sensors → Add Sensor → Heart Rate) or your Peloton’s heart-rate sensor pairing screen, choose “MyHRM”.
What it does
A real Bluetooth heart-rate sensor, powered by your Watch
MyHRM speaks the standard Bluetooth Heart Rate profile, so the devices you already own just see a heart-rate monitor.
Your Apple Watch is the sensor
MyHRM reads live heart rate from an Apple Watch workout — no chest strap, no extra hardware to charge or wear.
Standard Bluetooth heart-rate strap
Your iPhone advertises as a normal BLE Heart Rate sensor (service 0x180D). Any head unit or app that pairs a Bluetooth HRM can use it.
Real-time BPM relay
Heart rate travels Watch → iPhone → Bluetooth as you ride or run, using a mirrored HealthKit workout session for a steady live feed.
Pairs with Garmin & Peloton
Add “MyHRM” from the heart-rate sensor menu on a Garmin Edge or a Peloton, the same way you would add a chest strap.
Live status at a glance
One screen shows current BPM plus the state of each link — Apple Watch, Bluetooth sensor, and the connected head unit.
Refresh Sensor recovery
If a head unit drops the connection, Refresh Sensor rebuilds the Bluetooth advertisement and GATT service so you can reconnect quickly.
Works with Garmin & Peloton
Field-validated on the Garmin Edge 840 and Edge 1050 and the Peloton Bike+, and expected to work with most Garmin Edge head units and the Peloton Bike, Tread, and Row. Bluetooth only — no ANT+.
Nothing to sign up for, nothing stored
MyHRM reads heart rate from a HealthKit workout, relays it live over Bluetooth, and never writes it to a server. There is no account.
