🚀 Overview

The Period Tracker – Menstrual & Ovulation Health App is a fully featured source-code template designed to help developers, health-tech startups, and agencies launch a powerful app that tracks menstrual cycles, ovulation windows, fertility indicators, health symptoms, and overall wellness.

Inspired by leading apps such as Clue (which empowers users to understand their cycle and health) :contentReference[oaicite:1]{index=1} and Period Tracker – My Calendar (with features such as cycle predictions, ovulation tracking and reminders) :contentReference[oaicite:3]{index=3} this template offers a modern, GDPR-aware, user-centric solution spanning Android and iOS.

It is ideal for individuals, couples planning conception, people managing irregular cycles or hormonal conditions, and wellness platforms delivering value through tracking and insight. The description below ensures Experience (real-world relevance), Expertise (technical stack details), Authoritativeness (reference to established apps) and Trustworthiness (privacy & licensing clarity).

✨ Key Features

• 📅 Cycle & Period Calendar: Log past period dates, view upcoming predicted period, fertile window and ovulation day with visual calendar interface.
• 🔍 Ovulation & Fertility Window Predictor: Based on user-inputs (cycle length, luteal phase) the app estimates ovulation and fertility window. (See Clue’s ovulation guidance) :contentReference[oaicite:4]{index=4}
• 🧠 Symptom & Mood Tracking: Track dozens of symptoms (cramps, mood swings, headache), moods, energy, sleep and link them to cycle phases — supported by research showing self-tracked data has health insights. :contentReference[oaicite:5]{index=5}
• 🔔 Reminders & Notifications: Period start, upcoming fertile days, birth-control pill/patch/injection reminders, custom alerts for cycle irregularities.
• 📊 Analytics & Health Reports: View trends in cycle length, flow intensity, irregularities, export a PDF report for yourself or medical practitioner. (Feature common in apps) :contentReference[oaicite:6]{index=6}
• 🔐 Privacy-first & Data Security: Designed to comply with GDPR/CE-marked medical device standards (like Clue) :contentReference[oaicite:7]{index=7}. Sensitive health data is handled securely, with optional local-only storage mode.
• 📱 Cross-Platform / Multi-Account Support: Build for both Android and iOS; support multiple profiles (e.g., mother & daughter) inside one app. :contentReference[oaicite:8]{index=8}
• 🎨 Easy Customisation & White-Label Ready: Rebrand UI, adjust themes, customise tracking parameters (cycle length, luteal phase, symptom list) with minimal code changes.

⚙️ Technical Stack

• Mobile Framework: Flutter (Dart) or React Native (choose per source version) for Android & iOS single codebase.
• State Management: Provider / Bloc / GetX (depending on template) ensuring maintainable and modular architecture.
• Database / Storage: Local storage via SQLite, Hive or Realm for fast offline access; cloud sync optional (e.g., Firebase or REST API).
• Backend/API (optional): Node.js/Express or Laravel PHP for cloud sync, analytics, user authentication and push notifications—can operate offline if preferred.
• Push Notifications: Firebase Cloud Messaging (Android) and Apple Push Notification Service (iOS) for reminders and alerts.
• Server Requirements: Standard web hosting or cloud server (if backend used) with HTTPS/SSL enabled; mobile builds need Android Studio (or VS Code) + Xcode for iOS.

🧩 Installation Guide

1. Download the source code package to your local development environment.
2. Open in your IDE (Android Studio, VS Code) and run flutter pub get (or equivalent for React Native).
3. Configure app settings: app name, bundle/package ID, launcher icons, splash screen, theme colours.
4. If using cloud backend: setup server (Node/Laravel), configure database, create API endpoints and link to mobile app’s config.
5. Set up push notification credentials (Firebase, APNs) and connect to mobile build.
6. Build & test: run on emulator and physical devices for Android and iOS, test core flows: log period, symptom tracking, view predictions, receive reminder notifications.
7. Publish: generate release build (Android: .aab/.apk, iOS: .ipa) and upload to Google Play / Apple App Store (comply with health / wellness categories).
