3 Best Sleep Tracker Picks for Optimizing Your Sleep (2026)
I tested the top sleep wearables for every type of sleeper, including devices from Oura, Google Fitbit, and Eight Sleep.
The Oura Ring is hailed as the best overall sleep tracker due to its exceptional accuracy in assessing sleep quality. Sporting a multisensor suite that includes an 18-path multi-wavelength photoplethysmography (PPG) for monitoring blood oxygen levels (SpO2), heart rate, heart rate variability (HRV), respiratory rate, a negative temperature coefficient (NTC) thermistor for body temperature tracking, and a 3D accelerometer for capturing movement, the Oura Ring provides a comprehensive analysis of sleep stages and nighttime restlessness.
The device tracks total sleep time, time in bed, and sleep efficiency, presenting the data in a time graph with weekly or monthly trends. It also automatically detects naps, factoring them into the sleep score, a valuable feature. Comfort and user-friendliness are not compromised, as the ring can be comfortably worn to bed, and the app's interface is easy to navigate.
However, accessing advanced health metrics requires a monthly subscription of $6, which, while affordable, is still a recurring cost.
