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.
Coros Pace 4
Pros
- • Stated battery life of up to 19 days of daily use and 41 hours of GPS, at only 32 g with the nylon strap.
- • Records HRV, sleep stages and resting heart rate, with a recovery and training app and no fee mentioned on the product page.
- • Dual-frequency GPS and a 1.2-inch AMOLED touchscreen.
Cons
- • No independent validation found for sleep or HRV; wrist heart rate accuracy varies with effort.
- • No ECG or skin temperature, and SpO2 confirmed only by third-party sources.
- • No ANT+, no payments or third-party apps, and no full offline mapping according to reviews.
