Radio Frequency Detector is a free utility app developed by Saleem13. It is a mobile application that detects and receives radio frequency, also known as RF waves, making it useful for identifying hidden transmitters or unexpected RF activity, with a simple interface.

Detect nearby radio signals in seconds

The Radio Frequency Detector app functions as a simple frequency receiver that monitors for electromagnetic waves. Once it detects frequency waves, the app will display a message notifying you that a wave has been detected after approximately 60 seconds, providing a quick and easy way to identify nearby radio signals.

However, many users report unreliable detection, or it fails to detect what real RF equipment would detect. For example, a user held the radio near the phone and broadcast for over 60 seconds, and nothing happened. You can try the RF Signal Detector, which offers similar functionality.

Easy to use, but lacks accuracy

Radio Frequency Detector by Saleem13 is a free, easy-to-use app that detects and receives radio frequency waves. While it offers a simple interface and basic RF monitoring for curious users, its accuracy is limited, making it more of a novelty tool than a reliable alternative to professional RF detection equipment.
