Tech Stack

Programming Language

• Kotlin Multiplatform (KMP): The core logic is shared across Android, Desktop, and iOS using commonMain.

Frontend Frameworks

• Compose Multiplatform: Shared UI layer for rendering on Android and Desktop.
• Jetpack Compose: Used where platform-specific UI (like charts or permissions) is necessary on Android.

Background & Services

• Platform Services: Core service orchestrations and background work are abstracted into core:service to maximize logic reuse across targets, using platform-specific implementations (e.g., WorkManager/Service on Android) only where necessary.

Architecture

• MVI / Unidirectional Data Flow: Shared view models using the multiplatform androidx.lifecycle.ViewModel.
• JetBrains Navigation 3: Multiplatform fork for state-based, compose-first navigation without relying on NavController.

Dependency Injection

• Koin 4.2: Leverages Koin Annotations and the K2 Compiler Plugin for pure compile-time DI, completely replacing Hilt.

Database & Storage

• Room KMP: Shared local database using multiplatform DatabaseConstructor.
• Jetpack DataStore: Shared preferences.

Networking & Transport

• Ktor: Multiplatform HTTP client for web services and TCP streaming.
• Kable: Multiplatform BLE library used as the primary BLE transport for all targets (Android, Desktop, and future iOS).
• Coroutines & Flows: For asynchronous programming and state management.
