How we rated the Apple Watch
Our own assessment of a device we do not sell, weighted across six dimensions: accuracy 30 percent, coverage 20 percent, battery 15 percent, value 15 percent, comfort 10 percent, app and ecosystem 10 percent. Every score links to its source: independent testing, or the brand's own page for current-model specs and prices.
Apple Watch ECG is FDA cleared for atrial fibrillation, but independent treadmill testing shows its Cardio Fitness VO2 max estimate meaningfully underestimates lab values.
A 2025 PLOS ONE treadmill validation put the Apple Watch Cardio Fitness VO2 max at a mean absolute error of about 6.9 mL/kg/min versus a lab test, usable as a trend; its ECG app is separately FDA cleared for atrial fibrillation. PLOS ONE 2025 (VO2 max validation) ↗
One of the broadest health sensor suites for a watch, though SE 3 leaves out the ECG app, the Blood Oxygen app and hypertension notifications.
Apple's comparison lists the ECG app, Blood Oxygen app, hypertension notifications, sleep apnea notifications, wrist temperature sensing and a Vitals app with HRV on both Series 12 and Ultra 4. SE 3 keeps sleep apnea notifications and wrist temperature sensing, but not the ECG app, Blood Oxygen app, hypertension notifications or HRV in Vitals. Apple: compare Apple Watch models ↗
Endurance is the watch's defining weakness: Apple rates Series 12 at up to 24 hours and SE 3 at up to 18 hours of normal use, versus one to three weeks on rival sports watches.
Apple lists up to 24 hours of normal use for Series 12 (38 hours in Low Power Mode), up to 18 hours for SE 3 (32 hours) and up to 50 hours for Ultra 4 (84 hours), still well short of sports watches that run for weeks. Apple: compare Apple Watch models ↗
The Apple Watch is thin, light and comfortable all day, but daily charging forces a choice between overnight sleep tracking and topping up.
Apple lists Series 12 at 9.7 mm deep in aluminum or titanium and 32.2 grams for the 42 mm aluminum GPS model. It runs up to 24 hours on a charge, and Apple says five minutes of charging gives up to 10 hours of sleep tracking. Apple: Apple Watch Series 12 tech specs ↗
watchOS and HealthKit give coaching apps like Vora broad, permissioned read and write access to a central health data store shared across thousands of third party apps.
Apple states HealthKit provides a central repository for health and fitness data across iPhone, iPad and Apple Watch, and with user permission apps can read and write that data. Apple Developer: HealthKit ↗
Health features carry no subscription, but the full sensor set starts at $399 with Series 12, since the SE 3, from $249, has no ECG app, Blood Oxygen app or hypertension notifications.
Apple's store lists Apple Watch SE 3 from $249, Series 12 from $399 and Ultra 4 from $799. Apple Store: Apple Watch ↗
