Spiral Journey
Read full descriptionHide 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.

Verdict
The clearest difference is update cadence: Spiral Journey at every 3 weeks against Maxi Training's every 3 months. Maxi Training's advantage is iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
