## Overview

This is a .NET MAUI medication-tracking app: users register or log in, manage medications and reminders, and review medication history. Its main internal layers are the page-based UI, domain managers, SQLite persistence, and data models. The excerpts show manager-to-database calls and database table operations; the source index supports several UI-to-manager links. Notification behavior and some page details are unsampled, so those connections are limited to indexed references rather than inferred workflows.

Main entry points: [`Project/Services/DatabaseService.cs`](https://github.com/mh06a/medication-reminder-application/blob/main/Project/Services/DatabaseService.cs) (SQLite database service), [`Project/Controllers/MedicationManager.cs`](https://github.com/mh06a/medication-reminder-application/blob/main/Project/Controllers/MedicationManager.cs) (Medication manager), [`Project/Controllers/AuthManager.cs`](https://github.com/mh06a/medication-reminder-application/blob/main/Project/Controllers/AuthManager.cs) (Authentication), [`Project/Controllers/ReminderManager.cs`](https://github.com/mh06a/medication-reminder-application/blob/main/Project/Controllers/ReminderManager.cs) (Reminder manager)
