AirPods Pro 3 with heart rate measurement: what you need to activate and use

The AirPods Pro 3 arrived with one of the most talked-about features of the line: the ability to measure heart rate directly from the earbuds, without needing any extra wrist device. For those who already use Apple Watch to monitor health, it may seem redundant. But for those who don’t want, or can’t, carry a smartwatch all day, this is a significant change.

The feature uses optical sensors built into the earbud (the same ones that detect if the AirPod is in your ear) combined with algorithms processed locally by Apple’s chip. Think of it as a compact version of the Apple Watch heart rate sensor, adapted to work resting in the ear canal, which has good blood flow and facilitates reading. Apple has not disclosed the clinical accuracy of the sensor, so the feature is positioned as a wellness tool, not medical diagnosis.

This tutorial shows the step-by-step process to activate, configure, and use heart rate measurement on AirPods Pro 3, plus minimum system requirements and common issues that can block the process.

What you need before you start

Before looking for the option in the app, confirm that your setup meets the requirements. Trying to activate the feature without meeting these points will result in unavailable option or silent error.

Mandatory requirements:

• AirPods Pro 3 (the previous generation does not have the necessary sensors, according to Apple)
• iPhone with iOS 19 or higher (check the version in Settings > General > Software Update)
• AirPods firmware updated to the version compatible with the feature (update happens automatically when the earbud is in the case, charging and nearby the iPhone)
• Apple Health configured with your personal data (date of birth, biological sex), as the algorithm uses this information to calibrate the reading
• Face ID or Touch ID active, since health data requires authentication

If you purchased the device outside of Brazil, also check if the model has Anatel certification. Devices without the certification number may have health features blocked by regional restriction, in addition to not having legal warranty in the country. Apple Brazil sells certified versions; devices imported from other markets are at the buyer’s discretion.

Activating heart rate measurement through the Health app

The main path goes through the iPhone Health application, not the AirPods settings themselves. Many people look in the wrong place and give up thinking the feature doesn’t exist.

1. Open the Health app on your iPhone
2. Tap Browse (grid icon, in the lower right corner)
3. Select Heart Rate
4. Scroll down until you find AirPods Pro as a reading source
5. Tap Enable measurement by AirPods
6. Read and accept the terms; Apple makes clear that the feature does not replace medical evaluation
7. Authenticate with Face ID or Touch ID when prompted
8. Put the AirPods Pro 3 in your ears; the iPhone confirms the connection and starts initial calibration, which takes about 60 seconds

After calibration, the Health app begins recording periodic readings automatically while the earbud is in your ears. You don’t need to open any app to measure; the process is passive, just like the Apple Watch.

Configuring irregular heart rate notifications

Activating the sensor is only half the battle. The real value of the feature is in the automatic alerts, which notify you when your heart rate goes up or down outside the limits you define.

1. In the Health app, go to Browse > Heart Rate > Heart Rate Notifications
2. Enable High Heart Rate and set the limit (the default suggested by the app is 100 bpm for adults at rest)
3. Enable Low Heart Rate and set the limit (default suggested: 40 bpm)
4. Enable Irregular Heart Rate if you want to be alerted about possible atrial fibrillation episodes detected by the sensor; this specific alert requires you to be 22 years or older, according to Apple’s terms
5. Tap Done

Notifications appear as normal iPhone alerts, with the heart rate data and guidance to see a doctor if the pattern persists. For those who exercise and want to monitor training zones, the ideal is to cross this data with the Fitness app or with third-party apps that already integrate with HealthKit (Apple’s health platform that centralizes the data).

Using during physical activity

For workouts, the behavior is slightly different from passive monitoring. The AirPods Pro 3 tries to maintain continuous reading during exercise, but the quality of the data depends on the earbud being well-fitted, without gaps.

To ensure the best reading during activity:

• Use the silicone tips in the correct size (the app does the fit test in Settings > Bluetooth > AirPods Pro > Fit Test)
• Avoid moving the earbuds during your workout; each repositioning interrupts the reading for a few seconds while the sensor recalibrates
• If you’re using it alongside Apple Watch, the iPhone prioritizes the Watch as the heart rate source; to force AirPods reading, temporarily disable the Watch heart sensor in Settings > Health > Data Sources

Apple has not published accuracy comparisons between AirPods Pro 3 and Apple Watch for readings during exercise. Until independent research evaluates this with rigor, treat workout data as reference, not definitive measurement.

Common issues and how to solve them

The AirPods option doesn’t appear in the Health app

First, confirm that the firmware on your earbuds is up to date. To check: go to Settings > Bluetooth, tap the “i” next to AirPods Pro 3 and see the firmware version on the screen. Apple doesn’t manually indicate which version is the most recent, but if the earbud stayed in the case charging for at least an hour connected to Wi-Fi, the update should have occurred automatically.

If the firmware is current and the option still doesn’t appear, try forgetting and re-pairing the earbuds: Settings > Bluetooth > tap the “i” > Forget this device. Then open the case near your iPhone and follow the pairing process again.

The sensor keeps losing reading during the day

Unstable reading usually indicates a physical fit problem. Switch the tips to a smaller or larger size and redo the fit test. Another common cause is sweat or earwax buildup on the sensor; clean the earbuds with a lightly dampened microfiber cloth, paying attention to the tip area.

Data doesn’t appear in Apple Health after being activated

Check permissions: Settings > Privacy and Security > Health > Health (app) and confirm that “Heart Rate” has read and write permission enabled. If the Health app lost permission after an iOS update, this is not restored automatically.

The feature is not available on my model

If you have AirPods Pro 2 or any earlier version, the heart rate sensor doesn’t exist in the hardware. There’s no software update that adds this capability. Heart rate measurement is exclusive to AirPods Pro 3, according to Apple’s official specifications.

Frequently asked questions about heart rate measurement on AirPods Pro 3

Is AirPods Pro 3 heart rate data accurate enough for medical use?

Apple positions the feature as a wellness tool, not as a certified medical device. There is no publicly disclosed clinical validation by the manufacturer at this time. For real medical monitoring, your doctor will request a device certified for that purpose.

Does the feature work on Android or iPad?

No. Heart rate measurement by AirPods Pro 3 requires iPhone with iOS 19 or higher and Apple’s Health app. There’s no integration with Android or iPadOS, as the Health app doesn’t exist on the tablet system.

Does activating the sensor consume more AirPods battery?

According to Apple, the impact on battery life is minimal because the optical sensor already operates partially to detect if the earbud is in your ear. Heart rate reading reuses part of this infrastructure. For exact battery numbers with the feature active, consult the updated technical sheet on the Apple Brazil website, as this data may vary with firmware updates.

Do I need Apple Watch to use this feature?

No. AirPods Pro 3 work independently for heart rate measurement. If you already have an Apple Watch, the two devices can coexist, and the iPhone automatically chooses which source to prioritize based on detected activity. Those considering heart rate monitoring alternatives without Apple Watch can also look at smartbands like the Xiaomi Smart Band 10, which offers health monitoring for a fraction of the price, although without native integration with the Apple ecosystem.

Is the feature right for you?

Heart rate measurement on AirPods Pro 3 is welcome for those already in the Apple ecosystem and want to monitor health without adding a new device to their daily routine. The activation process is simple when requirements are in order; the biggest obstacle is usually outdated firmware or the wrong size tip.

If you’re thinking about buying AirPods Pro 3 in Brazil, know that the price varies greatly between national retail and importers. The US launch occurred with a suggested price in dollars that historically doesn’t translate directly to Brazilian reals given import taxes and ICMS. Always check if the product has Anatel certification before buying from unofficial resellers, especially because health features may be the first to be disabled on non-certified models.
