Cellular-Pro

Cellular-Pro is a real-time mobile signal monitoring tool for analyzing cellular networks. It supports testing across specified frequency bands, channels, or network conditions (as device capabilities allow) and displays wireless measurement parameters for NR, LTE, GSM, and WCDMA. It can parse and display network protocol information (where supported) and shows network events and labels, along with trajectory display and basic visualization features. The extension also provides network performance testing (throughput, latency, jitter) where supported by the device. Note that some features depend on device capabilities, and all tests are manually initiated by the user; the app does not run background network activity.
