How Sleep Tracking Technologies Compare
Smartwatches and ring-shaped devices are the most prevalent in the market and show consistent patterns in sleep tracking. Studies have found they have the best accuracy, sleep/wake detection and tracking of REM and light sleep. However, they often overestimate total sleep duration. Research shows wearables with multi-sensor fusion lead the pack for accuracy and advanced technology.

Wearables
Smart mattress pads or motion-sensing devices nearby have become increasingly popular. Studies have found that nearables tend to overestimate the time it takes to fall asleep and are the worst at detecting deep sleep. Studies have found the Withings Sleep Mat to be one of the most accurate nearables.
Nearables
Smartphone apps and devices that use built-in microphones, accelerometers or environmental sensors have the worst sleep/wake accuracy and sleep staging. In general, they’re only recommended for rough estimates and nothing more.
