Great news if you don't own an Apple Watch: you can absolutely use heart rate tracking on AirPods Pro 3 without one. The earbuds have their own built-in sensor that works independently with just your iPhone.
How the Sensor Works
The sensor inside AirPods Pro 3 uses infrared light to detect blood flow through your ear canal, pulsing 256 times per second. It's sophisticated technology packed into a remarkably small device.
Getting Started
Requirements:
- iPhone running iOS 19 or later
- Fitness app installed
To start tracking:
- Open the Fitness app
- Pick your workout type
- Tap to begin
Your AirPods automatically start tracking heart rate—no extra setup needed.
What You'll See
During workouts, your iPhone displays:
- Real-time heart rate
- Current heart rate zone
- Calories burned (calculated from heart rate data)
All data syncs to Apple Health for long-term tracking, and workouts count toward your Move ring goals.
Accuracy Tips
Testing shows AirPods Pro 3 can match chest strap accuracy during steady cardio. For best results:
- The ear tip that works best for heart rate may differ from what sounds best for music—prioritize sensor contact when working out
- Give the sensor a few seconds to establish baseline readings when you start
- Cold weather reduces accuracy since it limits blood flow to ears
If You Have Both Devices
When wearing AirPods Pro 3 and Apple Watch together, Apple's system automatically uses whichever sensor provides better readings at any moment.
Limitations
Heart rate tracking only works during active workouts—you won't get continuous all-day monitoring like Apple Watch provides. Advanced heart health features (like irregular rhythm detection) still require Apple Watch.
