WiFiAnalyzer is a mature, open-source Android application for analyzing Wi-Fi networks. It scans nearby access points, displays signal strength graphs (channel and time-based), provides channel ratings for optimizing Wi-Fi performance, and identifies vendor names via OUI lookup. The architecture is a standard Android app with Activities, Fragments, Navigation (drawer + bottom navigation), and a modular package structure. It uses Kotlin, AndroidX, and the Vico charting library for real-time graph rendering. The codebase exhibits strong software engineering practices: extensive unit and instrumented test coverage (over 50 test files), CI/CD with GitHub Actions, dependency version catalog, and high code quality standards enforced by lint and ktlint. While primarily an application, it processes Wi-Fi scan data to derive actionable insights (channel ratings, signal strength over time), giving it a minor data-research character. Key entry points include MainActivity and the ScannerService, which orchestrates periodic scanning and data transformation.
