# SyncOne

**SyncOne** is a modular and extensible mobile application built with **.NET MAUI** to manage SMS communication and processing in real-time. Designed with an intelligent, background-processing architecture, it supports cross-platform operation and integration with Language Models (LLMs) to enable offline AI-powered messaging.

---

## 📲 Features

- **Real-Time SMS Processing**  
  - Background service (`SmsService`) ensures continuous SMS operations even when the app is closed.  
  - Retry mechanism with exponential backoff for reliable delivery.

- **Platform-Agnostic Design**  
  Uses `ISmsService` as an abstraction layer for SMS operations, enabling cross-platform integration.

- **Extensible Architecture**  
  Modular components like `DatabaseService`, `ApiService`, and `ConfigurationService` promote maintainability and scalability.

- **Intelligent Integration**  
  Supports LLM-powered interactions—AI assistants, translation, customer support via SMS.
