Buying Guide

Sensor types matter

Choose trackers with both optical heart-rate sensors and blood-oxygen (SpO2) monitoring to get more complete sleep-stage and breathing-related data

Continuous 24/7 monitoring

Devices that offer round-the-clock heart-rate and overnight tracking capture interruptions and variability that single-point readings miss

Display readability

An AMOLED or larger high-contrast display (like 1.47") makes it easier to review sleep summaries and adjust settings without a phone

Companion app and data access

Confirm the tracker’s app provides clear sleep staging, downloadable trends, and export options for sharing with health professionals
