According to MacRumors, the latest update to the Google Health app for iOS now allows data to sync to Apple Health. The Google Health app collects information from wearables including Fitbit trackers and the Pixel Watch.
For health and fitness developers, this means Fitbit and Pixel Watch data may now flow into Apple HealthKit rather than staying siloed in Google's ecosystem, so you can potentially read that data through the standard HealthKit APIs without a separate Google integration. Worth checking whether the sync is real-time or batched and which specific metrics come through, since gaps there affect anything doing live coaching or trend analysis. If you're privacy-focused, note the data still passes through Google's app first, so be clear with users about that path.
