How Vitalstat Tracks Your Sleep
Vitalstat reads sleep data from your connected wearable device. Whether you wear an Apple Watch, Garmin watch, Polar device, or Oura Ring to bed, Vitalstat automatically pulls your sleep data and presents it in a clear, intuitive interface. No manual logging required — just wear your device and wake up to detailed insights.
Sleep Stages Breakdown
Every night, your body cycles through different sleep stages. Vitalstat breaks down your sleep into four stages:
- Deep Sleep — The most restorative stage. Essential for physical recovery, immune function, and memory consolidation.
- REM Sleep — When most dreaming occurs. Critical for cognitive function, emotional regulation, and learning.
- Light Sleep — Transitional stage between wake and deeper sleep. Important for memory processing and motor skills.
- Awake — Brief awakenings during the night. Some awakenings are normal, but excessive wake time can reduce sleep quality.
Sleep Score & What It Means
Vitalstat calculates a sleep score for each night that summarizes your overall sleep quality. The score considers total sleep duration, time spent in each sleep stage, heart rate patterns, and sleep consistency. Use your sleep score to track trends over weeks and months, and identify what habits lead to your best sleep.
Heart Rate During Sleep
Your heart rate during sleep reveals important information about your cardiovascular health and recovery. Vitalstat tracks your resting heart rate throughout the night, showing how it changes across sleep stages. A lower resting heart rate during sleep generally indicates better cardiovascular fitness and recovery.
Sleep Consistency & Trends
Consistency is key to good sleep. Vitalstat tracks your bedtime and wake time patterns over time, helping you build a regular sleep schedule. View weekly and monthly trends to understand how your sleep quality changes and what factors influence it.
HRV & Recovery From Sleep
Heart rate variability (HRV) measured during sleep is one of the most reliable indicators of recovery and readiness. Vitalstat uses your overnight HRV data to calculate recovery scores, helping you understand whether your body is prepared for intense training or needs more rest.

Frequently Asked Questions
What is the best app for tracking sleep on Apple Watch?
Vitalstat provides comprehensive sleep tracking for Apple Watch users, including sleep stages breakdown (Deep, REM, Light, Awake), heart rate monitoring during sleep, sleep scoring, and consistency tracking. It also aggregates sleep data from Garmin, Polar, and Oura Ring for a complete picture.
How accurate is sleep stage tracking?
Vitalstat relies on the sleep stage data provided by your wearable device. Apple Watch, Garmin, Polar, and Oura Ring all use accelerometer and heart rate sensors to detect sleep stages. While not as accurate as a clinical sleep study (polysomnography), consumer wearables provide a reliable indication of sleep quality and patterns over time.
What does the sleep score mean?
The sleep score is a single number (typically 0-100) that summarizes your overall sleep quality for a given night. It factors in total sleep duration, time in each sleep stage, sleep consistency, heart rate during sleep, and restfulness. A higher score indicates better quality sleep.
Can I track sleep from multiple devices?
Yes. Vitalstat can receive sleep data from Apple Watch, Garmin, Polar, and Oura Ring. If you use multiple devices, you can choose which source provides your sleep data, or let Vitalstat automatically select the most complete data source.
