# Next Step - New Feature Design Document

## Overview
This document outlines 5 new features designed to help families supporting a loved one through chemotherapy treatment.

## Feature 1: Enhanced Symptom Tracking with Trends & Insights

### Problem
Current symptom tracking is basic - users can log symptoms but have limited visibility into patterns, trends, or correlations.

### Solution
- **Detailed Symptom Logging**: Add duration, triggers
- **Trend Visualization**: 7/14/30-day charts with filtering
- **Pattern Detection**: Highlight when symptoms spike
- **Symptom Report**: Exportable PDF report for doctor visits

## Feature 2: Caregiver Coordination (Handoff Notes & Task Assignments)

### Problem
Families struggle to coordinate care, especially with multiple caregivers.

### Solution
- **Handoff Notes**: Quick shift-change notes
- **Task Assignments**: Assign tasks to specific caregivers
- **Caregiver Activity**: See who's doing what

## Feature 3: Treatment Milestone Tracker

### Problem
Chemo is a long journey - families need encouragement and a sense of progress.

### Solution
- **Treatment Plan**: Define treatment schedule (e.g., "12 cycles")
- **Visual Progress**: Progress bar showing % complete
- **Milestone Cards**: Celebrate wins

## Feature 4: Quick Access Emergency Widget

### Problem
Emergency info exists but requires navigation. In a real emergency, every second counts.

### Solution
- **Emergency Button**: Always-visible floating button
- **One-Tap Calling**: Direct dial for emergency contacts
- **Emergency Mode**: Simplified, high-contrast view

## Feature 5: Calendar Integration (iCal/ICS Export)

### Problem
Families use multiple calendars. Appointments in Next Step aren't visible in their regular calendar apps.

### Solution
- **Subscribe URL**: Personal ICS feed URL
- **Export Appointments**: Generate .ics files
- **Share Calendar**: Family members can subscribe
