## Description

Reads your Apple Health sleep data and draws it as a spiral that grows one turn per night. Everything runs on your iPhone. No accounts, no ads.

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.
