Project Overview

Many digestive issues, inflammation symptoms, and recurring discomforts may be related to diet. However, people often rely on memory when trying to identify potential triggers.

MoonEcho creates a simple daily record of meals and body conditions, helping users build long-term evidence for personal health insights.

The Problem

Food and symptom records are often separated, inconsistent, or forgotten.

The Goal

Make daily meal and health tracking fast enough to complete in under one minute.

The Outcome

A photo-first workflow with health status logging, meal history, and calendar review.

Core User Flow

The interface is designed as a clear step-by-step journey, from logging how the user feels to saving a meal and reviewing historical records.

  1. 1

    Log health status

    Select today’s condition, such as healthy, diarrhea, inflammation, or other symptoms.

  2. 2

    Add meal record

    Use the primary action button to capture a meal photo or upload from the photo library.

  3. 3

    Review and categorize

    Confirm the image, edit the food name, and assign breakfast, lunch, or dinner.

  4. 4

    Analyze history

    Review meals and health records by date to identify repeated patterns over time.

Key Features

MoonEcho combines behavior tracking and health status tracking into one unified system.

Future AI Opportunity

“You experienced digestive discomfort more often after meals containing dairy or fried food.”

As more data is collected, MoonEcho can evolve from a tracking tool into a personal health intelligence platform, helping users identify potential food sensitivities, recurring symptom patterns, and lifestyle correlations.

Design Reflection

The main design challenge was balancing data accuracy with low-effort daily use. By making photos the primary input and keeping health logging lightweight, the app encourages consistency while still producing structured data for future analysis.
