How it got here
2015–2020 · Modernization and architecture overhaul
This period was defined by a comprehensive modernization of the codebase, characterized by the migration to Jetpack Compose, Kotlin Coroutines, and a new navigation architecture. Legacy components, including the old database, dependency injection, and UI implementations, were systematically removed and replaced with modular, type-safe alternatives. The work also expanded the app's capabilities by integrating new tracking services and improving background task management.
