Sleep

The only smart ring that hears you sleep

Most smart rings track sleep with motion and heart rate. Adola adds a built-in PDM microphone that detects snoring, coughing, and breathing irregularities throughout the night -- data no other ring can capture.

How Adola tracks your sleep

Sleep staging

Deep, REM, light, and awake phases classified using HRV patterns, movement data from the 6-axis IMU, and skin temperature shifts. Comparable to clinical polysomnography staging.

Snore detection

The IM72D128 PDM microphone records audio events during sleep. On-device algorithms classify snoring episodes, frequency, and duration. Audio is processed locally and never uploaded.

Overnight SpO2

Continuous blood oxygen monitoring via the MAX30102 sensor. SpO2 dips during sleep can indicate breathing disruptions linked to sleep apnea.

Skin temperature

The TMP117 sensor tracks ±0.1°C changes in basal body temperature overnight. Useful for menstrual cycle tracking, illness detection, and circadian rhythm analysis.

Heart rate variability

Beat-to-beat HRV during sleep is the most accurate window into your autonomic nervous system. Adola measures RMSSD and tracks your baseline over time.

Why a microphone matters for sleep

An estimated 45% of adults snore occasionally, and up to 25% snore regularly. Chronic snoring is a primary symptom of obstructive sleep apnea, which affects approximately 30 million Americans but remains undiagnosed in 80% of cases.

Phone-based snore detection apps require leaving your phone on the nightstand and picking up ambient noise from partners, pets, and traffic. Adola's ring-mounted microphone sits directly on your finger, isolating your own breathing sounds from the environment.
