電波探知機 is a utility application designed for Android devices that provides real-time measurements of mobile phone and WiFi signal strength. This tool is particularly useful in identifying areas with strong and weak signal reception within buildings, allowing users to locate optimal spots for connectivity. The application displays signal strength in numerical form, making it easy to assess the quality of the signal at any given location.

In addition to visual feedback, 電波探知機 incorporates an audio feature that alerts users to signal conditions. It emits high-pitched sounds for strong signals and low-pitched sounds for weak signals, enabling users to gauge their connectivity through auditory cues. This dual approach of visual and auditory feedback makes the application versatile and user-friendly, catering to various preferences in monitoring signal strength.
