Spiral Journey

Features
Read full description

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? β€’ Reads from Apple Health: sleep stages, heart rate, HRV (SDNN), wrist temperature, daylight exposure, steps, workouts, menstrual cycle, high HR events. β€’ Draws the spiral flat 2D, logarithmic 2D, or 3D with perspective. Archimedean or logarithmic growth. β€’ 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. β€’ 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). β€’ NeuroSpiral 4D torus: sleep trajectory on a Clifford torus with 16 tesseract states. CSV export. β€’ Trends tab: this week vs last, night-by-night breakdown, Lomb-Scargle periodogram for detecting 24-hour, weekend, and 28-day cycles. β€’ Prediction: aligns your current week with similar past weeks and proposes bedtime and wake time for tonight. β€’ Coach tab: day summary and a proposed sleep window based on your chronotype. β€’ Widgets: spiral and circadian state on the home screen. β€’ Apple Watch: simplified spiral and 3D torus. β€’ Dream journal by voice (on-device transcription) or text. With iOS 26 and Apple Intelligence available, it summarizes patterns using local models. β€’ Peer comparison via Multipeer Connectivity: two nearby iPhones exchange aggregated metrics, not raw data. What it doesn't do: β€’ No user accounts. β€’ No data sent to any server. β€’ No advertising. β€’ 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.
