sleep tracker
Nocturnal rest measurer
A sleep tracker is a device or app that monitors sleep patterns, typically recording duration, quality, and sleep stages.
Most use motion sensors or heart rate data to estimate when you're in light, deep, or REM sleep.
My sleep tracker says I only got four hours of deep sleep last night.
Wearable fitness bands, smartwatches, and smartphone apps commonly include sleep tracking features.
