Buying Guide

Sensor accuracy matters

Choose trackers with continuous heart-rate and SpO2 monitoring — these sensors improve sleep-stage and breathing disturbance detection

A lightweight band and proper strap sizing reduce movement and improve data quality for sleep metrics

App and data export options

Prefer trackers with robust companion apps, exportable sleep reports, and third-party integrations for long-term trend analysis

Multi-day battery and charging

Longer battery life reduces interruptions to sleep tracking; consider how often you’ll need to charge based on your usage patterns
