Spiral Journey vs SunSync

Spiral Journey draws your Apple Health sleep data as a spiral that grows one turn per night. Drag a cursor through time and each turn colors in with that night's phases: deep, REM, light, and wake periods. What it does? • Reads from Apple Health: sleep stages, heart rate, HRV (SDNN), wrist temperature, daylight exposure, steps, workouts, menstrual cycle, high HR events. • Draws the spiral flat 2D, logarithmic 2D, or 3D with perspective. Archimedean or logarithmic growth. • DNA tab: RealityKit 3D double helix. Compare against yesterday, the weekly average, or your best night. With 2+ weeks of data it detects recurring patterns using DTW + agglomerative clustering and surfaces them as motifs with auto-generated names. • Sleep triangle: each 15-minute epoch sits between three vertices (Awake, REM, Deep). Light sleep (N2) lands in the interior. Vertex centers are calibrated with published data from 155+ subjects (HMC + Sleep-EDF). • NeuroSpiral 4D torus: sleep trajectory on a Clifford torus with 16 tesseract states. CSV export. • Trends tab: this week vs last, night-by-night breakdown, Lomb-Scargle periodogram for detecting 24-hour, weekend, and 28-day cycles. • Prediction: aligns your current week with similar past weeks and proposes bedtime and wake time for tonight. • Coach tab: day summary and a proposed sleep window based on your chronotype. • Widgets: spiral and circadian state on the home screen. • Apple Watch: simplified spiral and 3D torus. • Dream journal by voice (on-device transcription) or text. With iOS 26 and Apple Intelligence available, it summarizes patterns using local models. • Peer comparison via Multipeer Connectivity: two nearby iPhones exchange aggregated metrics, not raw data. What it doesn't do: • No user accounts. • No data sent to any server. • No advertising. • No in-app purchases. All analysis runs on your iPhone. Data only leaves the device if you enable iCloud Sync (optional, across your own devices). Languages: Spanish, English, Catalan, French, German, Japanese, Simplified Chinese, Arabic.
