+# Supplements Tracker
 
-A new Flutter project.
+A Flutter application designed to help you track your daily supplement intake, manage dosages, and set reminders. This app aims to provide a simple and intuitive way to stay on top of your supplement regimen.
+
+## Features
+
+- **Supplement Management**: Easily add, edit, and delete supplements, including details like name, dosage, and frequency.
+- **Intake Tracking**: Log your daily supplement intake, marking when you've taken your doses.
+- **Reminders**: Set up local notifications to remind you when it's time to take your supplements.
+- **Customizable Theme**: Switch between light and dark themes to suit your preference.
+- **Local Data Storage**: All your supplement data is stored locally on your device.
+
+## Technologies Used
+
+- **Flutter**: The UI toolkit used for building natively compiled applications for mobile, web, and desktop from a single codebase.
+- **Provider**: A robust state management solution for Flutter applications.
+- **sqflite**: For efficient local database persistence using SQLite.
+- **shared_preferences**: To persist user settings and preferences locally.
+- **flutter_local_notifications**: For scheduling and displaying local notifications to remind you about dosages.
+- **timezone**: Ensures accurate time zone handling for notification scheduling.
+- **intl**: For internationalization and flexible date/time formatting.
