|---|---|---|
| Our score | 82/100 | 78/100 |

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 4
Pros
- • Sleep tracking backed by studies against polysomnography, but carried out with earlier generations (Gen2 and Gen3): none of them validates the Ring 4 directly.
- • Titanium body 2.88 mm thick and 3.3 to 5.2 g depending on size, with no screen or vibrations: very unobtrusive for sleeping.
- • Typical battery life of 5 to 8 days according to the manufacturer, with 100 m water resistance.
Cons
- • The full app requires a membership: without it you only see three daily scores, the battery level and little else.
- • Titanium that scratches easily and a poor companion for strength training; according to specialist reviews, scratches are not covered by the warranty.
- • Workout tracking is less reliable than a sports watch, and some users report batteries that degrade over the months.
Samsung Galaxy Ring
Pros
- • No subscription: Samsung's official page mentions no paid subscription for the ring's features.
- • Very light: between 2.3 g (size 5) and 3.0 g (sizes 12 and 13), 7 mm wide and 2.6 mm thick, according to Samsung.
- • Official battery life of up to 6 days (sizes 5 to 11) and up to 7 days (sizes 12 and 13), with a charging case that shows the battery level.
Cons
- • Only works with Android phones (the Spanish product page states Android 11 or later); there is no official iPhone compatibility.
- • No published studies have been found that validate its sleep, HRV or temperature readings.
- • There are user reports of sharp battery loss and a high-profile case of a swollen battery, with no confirmed cause.
