Sleepcraft

Sleepcraft: Advanced Sleep Tracker & Analyzer Sleepcraft is a high-resolution utility for measuring sleep architecture and daytime activity. Designed for precision, the app provides a clinical-grade analysis of your sleep sessions using local, on-device processing to ensure total data privacy. Visual Session Mapping - 12-Hour Sleep Clock: View a high-resolution breakdown of sleep stages—Core, Deep, REM, and Awake—mapped onto a 12h clockface. - Sleep Stage Analysis: Monitor the duration and percentage of each sleep cycle to understand your nightly recovery. - Clinical Benchmarks: Evaluate your data against age-adjusted standards sourced from the NIH, CDC, and NHS. Activity and Sleep Correlation - Daytime Activity vs. Sleep Quality: Link your active energy and step count to subsequent sleep quality. - 90-Day Trend Analysis: Detect hidden patterns by analyzing 90 days of historical data from Apple Health. - Factor Tracking: Log lifestyle variables like caffeine, alcohol, exercise, and room temperature to correlate habits with physiological outcomes. Advanced HealthKit Integration Sleepcraft retrieves and processes biometric data directly from HealthKit, including: - Heart Rate & Resting Heart Rate - Heart Rate Variability (HRV) - Active Energy & Step Count - Sleep Duration & Regularity Precision Metrics - Regularity Index: Measure the consistency of your sleep schedule with 30-day tracking of onset and offset deviations. - Recovery Scoring: Analyze the 24-hour cycle of daytime strain and nightly recovery. Privacy-First Architecture: All biometric analysis is performed locally on your iPhone. Your health data never leaves your device. Why Sleepcraft? Unlike wellness apps that provide generalized advice, Sleepcraft is a precision recorder and analyzer. It is built for users who want to identify statistical links between their daily habits and their biological sleep quality.
