Everything MyHRM does today
MyHRM is focused: get an accurate live heart rate from your Apple Watch onto the device that needs it, reliably.
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.
Reconnect resilience
A brief Watch–iPhone reachability loss will not crash the app; live updates resume automatically once the link is back.
Automatic Garmin reconnect
If Garmin unsubscribes mid-ride, MyHRM retries on its own — fast for the first 30 seconds, then every 30 seconds after — and refreshes again whenever you bring the app to the foreground.
Long-outage warning
After 90 seconds of continuous Garmin disconnect, MyHRM shows an on-screen warning so you know to check the link and tap Refresh Sensor.
Broadcasts during your workout
Start broadcasting, start a Watch workout, and MyHRM keeps sending heart rate for the whole session.
On-device diagnostic logs
A protected local session log — BPM, connection states, reconnect attempts — helps troubleshoot pairing. It stays on your iPhone, is excluded from backups, and you can delete it anytime.
No account, nothing sent to a server
There is no sign-up. Heart rate is relayed live and never uploaded — only a local diagnostic log stays on your device, and that is yours to delete whenever you like.
MyHRM is free for 7 days. After the trial it's an auto-renewing subscription at $3.99 / year, billed through your App Store account and cancellable anytime in your Apple subscription settings.
