Frexello for Android

Frexello is a mobile utility designed for Android devices that focuses on cellular signal quality and coverage mapping. The application captures real-time network metrics such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR). It features interactive hex-grid maps powered by Mapbox, providing users with detailed local analysis and drive testing capabilities. Users can access Cell ID, Mobile Country Code (MCC), Mobile Network Code (MNC), and Location Area Code (LAC) details, along with options for KML and CSV data export while ensuring the anonymity of contributed points.

The app is particularly useful for both casual mobile users seeking improved reception and network technicians requiring portable tools for field analysis. By collecting live cellular measurements and overlaying them onto location-based maps, Frexello enables users to identify reception dead zones effectively. However, it does rely on an active GPS lock and network access to capture metrics and render maps, which could impact performance if the internet connection is unstable.
