Titan: AI Athletic Recovery

Stop guessing how hard to train. Titan is the privacy-first, on-device athletic coach built for iOS 26+ that turns your raw HealthKit data into actionable daily recovery and exertion guidance.

Unlike passive fitness trackers that only report what happened yesterday, Titan answers the three critical questions every athlete faces:
• "How hard should I train today considering my goals and injuries?"
• "Did my last workout actually improve my fitness?"
• "Why is my recovery low?"

INTELLIGENT RECOVERY & HRV SCIENCE

• Wake-Aware Body Battery: Tracks real-time energy reserves decaying from wake-up, with allostatic recharges for naps and mindfulness sessions.
• Tomorrow’s Forecast: AI-driven recovery projections calibrated to your unique baseline.
