FuelSync
Discover how your diet affects your health—privately.
Overview
FuelSync connects nutrition logging with Apple Health data to reveal personal correlations between what you eat and how your body responds. Unlike generic calorie counters, it shows you patterns like how protein affects your sleep quality or carbs impact your energy levels.
The Problem
Nutrition apps track calories in isolation. Health apps track metrics in isolation. Users have no way to connect the two and understand their personal diet-health relationships without manual correlation, sharing sensitive data, or complex setups.
The Solution
- Correlation Engine — Automatically analyzes relationships between nutrition and health metrics
- Personal Insights — Discovers patterns specific to your body (protein↔sleep, carbs↔energy)
- Privacy-First — Zero cloud, zero analytics, zero third-party sharing
- Apple Health Integration — Seamless sync with sleep, heart rate, HRV, steps, weight
- Pre-Loaded Catalog — 160+ meals ready to log, plus custom meal creation
