Ultrasound Detector by Koopango is a lightweight Android app that allows users to analyze the ultrasound activity in their environment. With the help of an algorithm, the app detects the presence of ultrasound activity and categorizes it into three levels: Low, Medium, and High.

On Low activity, there is no ultrasound activity detected. On High activity, there is some form of ultrasound activity, which is likely used to enhance the user experience. On Medium activity, ultrasound is detected, but its purpose is uncertain. It could be ultrasound communication or a maintenance signal for checking the health of a loudspeaker.

The main goal of this app is to provide users with control over their device's use of ultrasound data communication, a popular medium for communication. By offering transparency, Ultrasound Detector allows users to understand and manage the ultrasound features utilized by apps powered by Koopango.

Additionally, the app enables users to check the microphone permission of their installed apps, helping them identify which apps may have the ability to communicate using ultrasound. If any doubts arise, users are encouraged to contact the developers of those apps for further clarification. This app aims to empower users while ensuring a pleasant user experience.
