FuelSync

Discover how your diet affects your health—privately.

Overview

What this file is about.

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

The friction before the build.

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.
