Three Questions Apple Health Can't Answer

Titan turns wearable data into active daily answers—engineered for athletes who demand actionable context, not generic step counters.

Titan Answer 01

Goal-Based Target Exertion & Injury Caps

Titan moves beyond passive retrospective dashboards. Select Build, Taper, or Maintenance mode to automatically scale daily exertion targets. When injured, Titan's Safety Protocol deterministically clamps target exertion to ≤3.0 (Active Recovery) and readiness to 80/100 to prevent overtraining.

  • ✓Goal Modes: Build (+15%), Taper (-30%), Maintenance
  • ✓Injury Safety Protocol: Automatic -40% exertion cap
  • ✓Daily Target Exertion score on a piecewise 0-10 scale

The bio-metric engine

Offline-first signal processing with TRIMP-style exertion, load estimation, and metrics tuned for athletes—not casual step counts.

  • True HRV (rMSSD)

    Parasympathetic tone from clinical-grade raw beat-to-beat rMSSD—not SDNN-style summary statistics dressed up as insight.

  • Behavioral Context Engine

    Sixteen core lifestyle tags—alcohol, late meals, sickness, job stress, and more—correlated with physiology so patterns become actionable.

  • Injury Safety Protocol

    Deterministic guardrails: Target Exertion clamped to ≤3.0 (Active Recovery) and Readiness capped at 80/100 when the protocol applies.
