Your Guide to
Better Sleep

Sleep trackers turn a fuzzy “I slept okay” into data you can act on: sleep stages, heart-rate variability, breathing rate, and a morning readiness score. The best one depends on how you sleep and how much you want to think about it. A ring like the Oura disappears on your finger and nails sleep staging; a band like Whoop is built around recovery; a smartwatch (Garmin, Amazfit) pulls double duty for workouts. We focus on what matters for sleep specifically: tracking accuracy, battery life that survives overnight wear, how deep the app’s insights go, and whether the daily score actually nudges better habits. Start with the roundups to shortlist, then dig into the individual reviews.
