No extra hardware
The Sensor Is Already in Your Ears
AirPods Pro sit in your ear canal — unaffected by wrist motion, grip pressure, or cold skin. No chest strap to soak through, no extra device to charge. Just the buds you already train with.
You already train with AirPods Pro in. AirHRM reads their heart rate and broadcasts it as a standard Bluetooth sensor — the same signal a chest strap sends, readable by any equipment that accepts one.
AirPods Pro 3 already measure your heart rate. AirHRM rebroadcasts it from your iPhone as a standard Bluetooth sensor — the same signal a chest strap sends. Your Peloton, Concept2, gym machine, or bike computer pairs with it and reads live BPM. Setup takes about a minute.
Pair it once. After that, it's the same three moves before every session.
Open AirHRM on your iPhone and tap Start. That's what makes your phone visible as a heart rate sensor.
On your rower, bike, treadmill, elliptical, or bike computer — search for a Bluetooth heart rate sensor and select AirHRM.
Your heart rate streams in the background. Lock your phone, pocket it, and go.
For anyone who trains with AirPods Pro and equipment that reads heart rate through Bluetooth.
No extra hardware

Glance-able
Your live heart rate stays visible on the Lock Screen and Dynamic Island throughout your session. No need to unlock.
Lock your phone or switch apps — AirHRM keeps broadcasting in the background.
No analytics, no zones. Your equipment handles that. AirHRM just bridges heart rate.
Concept2 PM5, Peloton, NordicTrack and other iFit machines, gym cardio consoles, treadmills, ellipticals, indoor training apps on a second device, and cycling computers — if it pairs to a standard Bluetooth heart rate sensor, it works. iPhones behave a bit differently than chest straps; check the list if you're unsure.
If your device supports BLE heart rate sensors, just give it a try — the 7-day free trial is risk-free. Follow the general pairing guide to get started. Either way, if you find out it works or doesn't work, let me know and I'll add it to the list:
This app is amazing!

Finally don't need a chest strap for accurate HR on my Garmin — the AirPods Pro integration just works. Huge upgrade for my setup.

Clever app that solves a problem

I have the Garmin Edge 130 and I followed the setup video and it works seamlessly. Really glad I don't have to wear an additional HR monitor to get this data into Garmin.

Any equipment that pairs to a standard Bluetooth Low Energy heart rate sensor: Peloton Bike and Tread, Concept2 PM5, NordicTrack and iFit machines, treadmills and ellipticals with BLE consoles, many commercial gym machines, Zwift or other training apps on a second device, Garmin Edge, Wahoo ELEMNT, and Hammerhead Karoo — model and firmware vary.

No. After your equipment connects, you can lock the phone or switch apps. AirHRM keeps broadcasting in the background until you tap Stop.
Yes — seven days free. You are not charged if you cancel before the trial ends.
An iPhone running iOS 26 or later, AirPods Pro that share heart rate with Apple Health, and the AirHRM app.
Most Garmin Edge units only allow one Bluetooth connection to your iPhone for phone features. You often choose between AirHRM or Garmin Connect live features during a session.
The Garmin guide has the workaround — it becomes routine quickly.
