Sleep Score and Trends

Smart Ring Pro summarizes each night into a sleep score – a simple yet powerful metric of how restorative your sleep has been. The score is based on the quality of your sleep, from sleep stages and continuity to your body's recovery.

Sleep Stages

Analyzes the balance between light, deep, and REM sleep.

Continuity

Measures how uninterrupted the night was, e.g., number of awakenings.

HRV and Heart Rate

Shows how well the body recovered during the night.

Temperature

Detects variations that can affect sleep quality.

Daily View

See the night's score and detailed graphs about your rest.

Weekly Trends

Discover patterns – do you sleep worse on certain days?

Monthly Overview

Track long-term changes and see how your lifestyle affects sleep.

Personal Baseline

The ring learns what is normal for you for more accurate analyses.

The Technology Behind – Why Smart Ring Pro Works

Smart Ring Pro is built with advanced sensor technology and intelligent algorithms that together make the sleep analysis unique. Where common apps often guess based on calendar data, Smart Ring Pro measures actual biological signals in real-time.

Precision Through Sensors

Pulse Sensor (HX3918): Captures your resting heart rate and heart rate variability (HRV) to show how your body is recovering.
Temperature Sensor: With an accuracy of ±0.005 °C, even small changes can be registered, which is crucial for understanding circadian rhythm and cycle changes.
G-Sensor (ST LIS2DW12): Tracks movements during the night to identify when you fall asleep, wake up, and which sleep stage you are in.

Algorithms That Interpret Your Body

All signals – pulse, temperature, and movement – are sent from the ring to the app, where an advanced algorithm analyzes the data and transforms it into clear insights:

Sleep stages (light, deep, REM)
Sleep score based on quality and recovery
Personalized recommendations for better rest

The Result

Through the combination of high-precision sensors and intelligent analysis models, you get a comprehensive picture of your sleep and recovery – something that common apps or simpler wearables cannot match.
