The App detects ultrasound signals 20-150 KHz in foreground-background modes.

UltraSound Detector is a powerful app designed to detect ultrasound acoustic signals above a user-defined frequency (default above 18 KHz). It helps users verify ultrasonic electronic pest repellents, locate leaks in AC and refrigeration systems by detecting ultrasonic hissing sounds, and identify ultrasonic cross-device tracking technologies used in ads and stores. Additionally, it can detect voice-to-skull devices and ultrasonic weapons that cause physical discomfort.

The app features ad-free usage, real-time signal level indication, vibration alarms, an automatic event log with spectrum and location data, and can convert ultrasonic signals into audible sounds. It supports both foreground and background monitoring modes, continuing detection even when the device screen is off, and includes adjustable frequency ranges, battery consumption settings, and comprehensive spectrum analysis views (spectrum, waterfall, oscilloscope). UltraSound Detector is compatible with internal microphones and external ultrasound sensors, supporting detection up to 150 KHz.

Pros

App is user-friendly and free of ads, providing a clean user experience.
Effective at detecting ultrasound frequencies beyond typical device microphone capabilities.
Minimal impact on battery life, suitable for daily use.
Feature-rich with various detection modes and functions like frequency transfer to audible sound.
Useful for practical applications such as leak detection, device testing, and locating high-frequency sources.

Cons

App has grammatical and spelling errors which reduce credibility and user trust.
Log feature for recording detected frequencies and events is insufficient or non-functional, lacking proper file attachment and time-stamped records.
Frequency threshold adjustment is not intuitive, lacking manual input options and requiring improvement in UI/UX.
