Google Pixel Watch users report ‘hallucinated’ fitness data after March update

🔬 Health & Fitness Research

Google‘s lab just proved smartphone cameras can hit clinical-grade heart rate accuracy, but fitness tech knows the real test—whether people actually ditch their watches for their phones when it counts, not just in controlled studies.

Marty’s Take:

The narrative is wrong: this isn’t a Garmin Fenix 8 Pro killer. PHRM captures resting heart rate from a phone held still—not continuous HR during your tempo run. Anyone comparing fitness trackers right now has no reason to pause. The actual disruption targets the 80% of adults who’ll never buy a wearable—and that’s a far bigger market than the one Google’s headline implies.
