A free browsers app for Android, by Saleem13

This app detects frequency waves within one minute, which, doesn’t involve too much waiting on the user’s end. When these waves are picked up by the application, a small pop-up appears at the bottom of the screen that reads “frequency wave detected and received.” 

Given its straightforward usage, this tool doesn’t appear to require technical knowledge from the user. The user interface is simple as it doesn’t require you to tap several buttons or navigate menus for the tool to detect and receive frequency waves. Hence, Radio Frequency Detector is perfect for users who want a no-fuss application on their devices. This tool is available for free on the Play Store.
