Each score comes from its full review, with its sources and criteria. The two scores are only comparable within the same type of product.

Oura Ring 5

Pros

  • • More discreet than the Ring 4: 6.09 mm wide, 2.28 mm thick and from 2 g according to Oura, versus the Ring 4’s 7.9 mm and about 2.88 mm; several reviews agree it is less noticeable.
  • • Official battery life of 6 to 9 days; in the attributed review tests, between roughly a week and a little over seven days in a size 11.
  • • IP68 water resistance down to 100 m and six finishes, all titanium.

Cons

  • • No published independent validation of the Ring 5: the accuracy improvements (12% more accuracy in overnight HRV, according to Oura) are the company’s own figures with no methodology.
  • • The full app requires a membership: without it you only see three scores, the battery and little else, and the fee cannot be paused.
  • • Fewer sizes than the Ring 4 (6 to 13, versus 4 to 15) and different sizing: the Ring 4 kit does not work.

Apple Watch Ultra 3

Pros

  • • Very accurate GPS in one specialist outlet test (exactly 2.0 miles on a 2-mile reference loop) and heart rate within ±1 bpm of a Polar H10 chest strap on average.
  • • ECG, hypertension alert and apnea alert with FDA clearance (Apple lists them as available in Spain, although it does not detail which clearance supports them in the EU); the ECG also has a clinical trial from Apple (98.3% sensitivity for atrial fibrillation and 99.6% specificity in sinus rhythm, in classifiable readings).
  • • No mandatory fee: data and health features are viewed in the iPhone Health app.

Cons

  • • Short battery for an adventure watch: Apple states 42 hours and a specialist outlet measured 16 hours of continuous GPS.
  • • Works only with iPhone, and the sleep, HRV and temperature features have no published validation for this model.
  • • It is the previous generation: the Ultra 4 is already on sale with a higher stated battery life and renewed sensors.
