Metabolic Profiling

The Premium tier unlocks 12 specialized calculators beyond the free tier:

• Body Composition Predictor: Uses wrist, neck, and waist measurements to estimate body fat percentage
• TDEE Precision Calculator: Adjusts for training phase, menstrual cycle (for applicable users), and activity variability
• Macronutrient Optimizer: Generates protein/carb/fat targets based on training goals and dietary preferences
• Calorie Deficit Strategist: Calculates adaptive deficit ranges that prevent metabolic adaptation

Injury Risk Assessment

The musculoskeletal calculator evaluates movement patterns and training load to predict overuse injury probability with 78% accuracy.

Adaptive Goal Strategy Triage

The AI analyzes your biometric trends, training consistency, and recovery metrics to generate personalized weekly plans. Key capabilities:

• Load Management: Adjusts training volume based on HRV trends and sleep quality
• Nutrition Timing: Recommends meal timing around workouts based on circadian data
• Injury Prevention: Flags movement imbalances before they become injuries
• Motivation Matching: Identifies whether you respond to challenge-based or achievement-based incentives

Conversational Assistant

The AI Coach engages in natural dialogue about:

• Exercise routine modifications
• Nutrition strategy adjustments
• Recovery protocol recommendations
• Progress analysis and celebration

Unified Vitality Index

Premium members access the Vitality Index—a composite score aggregating:

• Cardiovascular fitness (estimated VO2 max)
• Metabolic health (glucose stability, lipid profile trends)
• Musculoskeletal function (strength ratios, mobility scores)
• Sleep quality (duration, efficiency, HRV-derived recovery)
• Nutritional adequacy (micronutrient intake vs. targets)

Trend Analysis

• 90-day rolling averages: Smooth out daily fluctuations to reveal true progress
• Correlation mapping: Discover how sleep affects performance, how nutrition impacts recovery
• Benchmarking: Compare your metrics to age- and gender-matched normative data

Wearable Sync
