> From a hardware standpoint third party fitness trackers with full integration into iHealth and third party ear buds with the same (or better) features than airpods.

As someone who makes apps in the health space, I couldn’t care less if other tracker data was integrated into HealthKit. HealthKit honestly sucks - it's some bastard of objc naming schemes and methods jammed into Swift. The async is horrible to debug, too. No one has a good time in HK.

The issue with other trackers is that they are more locked down than Apple. You can't just get HR from Oura for instance - and that's not a health kit issue either.
