The AGEs/antioxidant-style index split reviewers sharply, with some calling it interesting or distinctive and others saying it was confusing, under-explained, or useless.
Pros: display quality, durability
Cons: cross-platform compatibility, antioxidant index
Antioxidant Index was the weakest new health feature overall, with reviewers calling it interesting or quick but repeatedly questioning usefulness, consistency, and anxiety potential.
Pros: third-party app support, heart rate accuracy
Cons: music controls, cross-platform compatibility
Only the one-year review gave opinionated evidence on antioxidant tracking, and it was lukewarm because the reviewer had barely used it and noted it was not passive.
Pros: build quality, software smoothness
Cons: stress tracking, blood oxygen tracking
The antioxidant index is consistently weak, with several reviewers calling it low-value, inaccurate, gimmicky, or only marginally responsive.
Pros: LTE connectivity, pairing reliability
Cons: antioxidant index, blood oxygen tracking
