Hey everyone
I'm working on a health app that's heavily focused on HRV tracking and analysis, and I'm trying to figure out what's actually possible with AirPods Pro 3 from a developer standpoint. The hardware clearly has a much better heart rate sensor than the previous generation, but I'm hitting some walls when it comes to actually accessing the data I need.
So here's the situation I'm dealing with: When I query HealthKit for HRV samples, I'm not seeing anything coming from AirPods Pro 3. The device is obviously capable of tracking heart rate continuously during workouts and listening sessions, and from what I've read about the hardware, it should theoretically be able to capture the inter-beat intervals needed for HRV calculation. But either that data isn't being processed on-device, or it's just not being made available through the standard HealthKit data types that third-party apps can access.
What I'm really after is either direct HRV metrics (like SDNN, which Apple Watch already provides through HKQuantityTypeIdentifierHeartRateVariabilitySDNN) or even better, access to the raw R-R interval data. With R-R intervals, I could calculate RMSSD, pNN50, and other time-domain and frequency-domain HRV metrics that are super valuable for tracking recovery, autonomic nervous system balance, and stress levels. This would be especially useful since a lot of users wear AirPods during activities when they're not wearing their Apple Watch.
Has anyone managed to find a way to pull this data from AirPods Pro 3? Are there any private frameworks or entitlements I should be looking into? Or is this just fundamentally not exposed to developers at the OS level right now?
I've gone through the HealthKit documentation pretty thoroughly and haven't found anything that specifically addresses this, but I'm wondering if I'm missing something or if there are any known workarounds.
I'm also curious if anyone has heard anything from Apple about future plans to expose this data. It seems like a missed opportunity given how capable the hardware is and how much value developers could provide with access to this physiological data. Would love to hear if anyone else is working on similar features or has insights into the technical limitations here.
