Understand your nights to master your days. Visualize sleep stages, monitor vital health metrics, and check your recovery at a glance with Home Screen widgets.
Waking up refreshed starts with understanding how you rest. Nocty transforms your nightly data into clear, actionable insights. By combining advanced sleep stage analysis with key health vitals, we give you a complete picture of your nightly recharge without the complexity.
[Sleep Balance] One night doesn't tell the whole story. We track your cumulative sleep over time to calculate your Sleep Debt or Surplus.
[Your Daily Sleep Score] Stop guessing how well you slept. We distill your night into a simple, easy-to-understand Sleep Score. Use it to gauge your energy levels and plan your day.
[Detailed Stage Analysis] Deep dive into your hypnogram. Visualize exactly how much time you spent in:
- Deep Sleep: For physical recovery.
- REM Sleep: For mental clarity and dreaming.
- Core/Light Sleep: The foundation of your rest.
- Awake Time: See interruptions you might not remember.
[Vital Health Metrics] We monitor the metrics that matter for your long-term health:
- Resting Heart Rate: Track cardiovascular health.
- Heart Rate Variability (HRV): A key indicator of recovery and stress.
- Respiration Rate: Keep an eye on nightly breathing patterns.
- Blood Oxygen (SpO2): Monitor breathing efficiency.
[Beautiful Widgets] Keep your insights front and center. Customize your Home Screen with elegant widgets that display your Sleep Score and Vitals at a glance.
Your health data is sensitive, and we treat it that way. Nocty integrates seamlessly with Apple Health to read your data securely. Your sleep analysis happens on your device.
