Best all-round smartwatch
A broad, unusually well-validated set of cleared cardiac and sleep features with no health paywall — held back on the empowerment axis by hard iPhone lock-in, clunky data export, and a blood-oxygen feature caught in litigation.
What it measures
HR, HRV, ECG, SpO2 (redesigned), wrist temperature, sleep stages + sleep-apnea risk, respiratory rate, cardio fitness (VO2max estimate).
Regulatory status
FDA-cleared ECG (De Novo), AFib History, irregular-rhythm notifications, and sleep-apnea risk (De Novo, 2024). SpO2 is wellness-only and was US-banned then re-enabled via a redesign; its legal status remains contested.
Validation & accuracy
Among the best-studied consumer wearables (living meta-analyses). SpO2 is weaker — low hypoxia sensitivity in hospitalized patients and documented skin-tone bias.
Data control & export
Health app exports an XML ZIP (raw but hard to use); ECG exports a clinician PDF; HealthKit/FHIR integration exists. No simple one-click full-data clinician export.
Wearability & battery
Full touchscreen smartwatch with the broadest app ecosystem here — notifications, payments, apps, fitness. ~18–36 hr battery means near-daily charging, the main friction.
Cost & access
Core health metrics are free — no paywall for ECG, AFib, sleep apnea, or sleep stages. Fitness+ ($9.99/mo) is optional and workout-only.
Who it serves
Generous with free clinical features and privacy-protective storage, but requires an iPhone and makes whole-data portability cumbersome.
Who is left out or burdened
iPhone required (no Android); XML export is unwieldy; SpO2 unequal across skin tones and legally unstable.
✓ Strengths
- Broadest set of FDA-cleared cardiac + sleep features of any consumer watch
- Among the best independently validated wearables
- No subscription paywall on health features; privacy-protective storage
- Most capable everyday smartwatch and app ecosystem
✕ Weaknesses
- iPhone-only — hard ecosystem lock-in, no Android
- Whole-data export is an unwieldy XML archive
- SpO2 weak for hypoxia, shows skin-tone bias, legally unstable
- ~18–36 hr battery means near-daily charging
72
Why this clinical score. Multiple De Novo/cleared cardiac and sleep features with strong independent validation; capped by single-lead ECG and a weak, contested SpO2.
64
Why this empowerment score. No health paywall is a real plus, but iPhone-only lock-in plus clunky XML-only export and the SpO2 instability pull the empowerment score to the middle.
82
Why this everyday score. The most capable everyday device of the group — huge app ecosystem and polish — with daily charging the only real drag.
Latest news
Reviews & coverage
Consistently rated the most capable all-round smartwatch: reviewers praise the FDA-cleared ECG and AFib history, fall/crash detection, and a vast app ecosystem. The recurring caveats are roughly a day of battery life and that the best health features stay locked to iPhone owners.
