Our Take
Gen 4 is the benchmark in sleep-tracking wearables. The form factor is the differentiator, a ring is the only wearable people actually wear 24/7 including to bed, where the data matters most. Heart rate, HRV, body temperature, and SpO2 from a finger sensor are within the trend-accuracy band of medical-grade equipment. The 7-day battery is 5-7x longer than any wrist wearable; you can forget about charging.
Pros
- 7-day battery (vs 1-2 days for wrist wearables)
- Continuous body temperature (useful for cycle and illness)
- Comfortable to wear to bed
- Best-in-class sleep stage detection per third-party comparisons
Cons
- Subscription ($5.99/mo) required for full analytics
- Smaller form factor = no screen, smaller battery vs smartwatches
