Dia-Log: Digital Health Tracking & Outbreak Intelligence

Dia-Log is a specialized, privacy-first mobile utility designed for tracking gastrointestinal health and monitoring community wellness trends. By combining the clinically recognized Bristol Stool Chart with real-time geospatial data, Dia-Log allows users to manage their personal health while contributing to a collective "Public Trends" map that identifies potential local outbreaks.

1. The Description File (DESCRIPTION.md)

Core Purpose: To bridge the gap between personal health logging and public health awareness. Dia-Log simplifies the process of recording digestive data and uses anonymized aggregation to alert users when a specific geographic area shows signs of a viral or bacterial outbreak (e.g., Norovirus or food poisoning).

Key Features:

Rapid Logging: A "three-tap" entry system using the Bristol Stool Scale.

Privacy-Centric Auth: Uses Firebase Anonymous Authentication—no emails or passwords required to start.

Geospatial Intelligence: Utilizes Geohashing to map reports without exposing a user's exact street address.

Outbreak Detection: An automated logic engine that flags areas when reports exceed a specific density threshold.

Visual Analytics: A dynamic dashboard showing the "Public Trends" and average health scores of the surrounding community.

2. The User Manual (USER_MANUAL.md)

Getting Started

Launch the App: Upon opening, the app automatically signs you in as an anonymous guest.

Making a Report

Select Your Score: Choose a number from 1–7 based on the Bristol Stool Chart.

Note: 1-2 indicates constipation; 3-4 is ideal; 5-7 indicates diarrhea.

Select Symptoms: Tap the tags that apply (e.g., "Cramping," "Nausea," "Diarrhea").

Submit: Tap the Commit button. The app will capture your current latitude/longitude and bundle it into a geohash.

Understanding the Map/Trends

Green/Normal: The community average is within the 3-4 range.

Red/Outbreak: If isOutbreak is true, the app will display a warning. This occurs when multiple reports with high Bristol scores (6-7) are recorded in the same geohash within a short timeframe.

Dia-Log is a community-driven health intelligence tool designed to turn individual wellness tracking into a collective early-warning system.

The app serves two main purposes:

Personal Tracking: It provides a frictionless way to log digestive health metrics using the clinically recognized Bristol Stool Scale.

Community Protection: It aggregates anonymized data to create a "live" health map. If multiple users in a specific neighborhood report symptoms simultaneously, the app identifies a potential Local Outbreak, allowing users to make informed decisions about food safety and public exposure.

📖 User Manual: How to Use Dia-Log

1. Your Daily Dashboard

When you open the app, you are greeted with the Community Health Status.

Regional Average: See the current average health score for your general area.

Outbreak Alerts: If the indicator turns red, a high volume of symptoms has been reported nearby.

2. Submitting a Report

Reporting takes less than five seconds to ensure you can stay consistent:

Identify: Match your experience to the 1–7 scale on the screen.

Detail: Tap any relevant symptoms (e.g., "Cramping" or "Nausea").

Submit: Hit the Commit button. Your location is automatically processed into a generalized region to protect your specific address while still contributing to the local map.

3. Privacy & Security

No Accounts Needed: Dia-Log uses secure guest access. You don’t need to provide an email, phone number, or password to use the app.

Location Privacy: The app does not share your exact GPS coordinates. It rounds your location to a general "sector" to keep the community map accurate without compromising your home or office location.
