WhiteShield enables you to estimate the noise level in your environment, calculate the level of microphone suppression, and produce audio interference of a needed volume to prevent recording conversations on a phone. The application includes a "Faraday cage" mode, exclusively designed for incorporation with shielding devices. Warning, this app generates high volume noise! Do not use it with headphones. ‣ Intuitive and user-friendly interface; ‣ Unifies a decibel meter and white noise generator in a single application; ‣ Ideally suited for use with shielding boxes or cases; ‣ Effectively counters unauthorized conversation recordings; ‣ Minimizes the possibility of extracting useful signals (speech) from recording. What's New: - Microphone suppression level estimate added; - Interface has been refreshed; - Bug fixes.

RF Pro Faraday Bag Tester – Ensure Your Devices Are Secure The Faraday Bag Tester app provides a reliable way to verify the effectiveness of Faraday bags by detecting signal leaks from your device. Whether for personal privacy, security compliance, or forensic applications, this tool helps confirm that your device remains isolated from external communication networks. Key Features: • Comprehensive Signal Testing – Detects WiFi, Cellular, GPS, and Bluetooth signals to assess shielding effectiveness. • Real-Time Analysis – Continuously monitors and records signal strength before and during testing. • Clear Visual Indicators – Displays test results with signal strength graphs and status icons. • Step-by-Step Guidance – Simple instructions to ensure accurate testing procedures. • Quick Retest Function – Easily restart the test to verify results. How It Works: 1. Press “Start Test” and place the device inside the Faraday bag before the countdown ends. 2. The app will emit a series of beeps, signaling the start of the testing phase. 3. During the test, the app scans for any detectable signals. 4. A chime will indicate the test has concluded, and results will be displayed. 5. Review the signal strength readings to determine if the Faraday bag is effectively blocking transmissions. Who Should Use This App? • Privacy-conscious individuals ensuring their devices remain undetectable. • Security professionals testing Faraday enclosures for compliance. • Forensic analysts verifying signal isolation for evidence protection. • Organizations implementing secure communications and data protection policies. The Faraday Bag Tester offers a straightforward yet powerful method to validate signal shielding performance. Download today to ensure your device security.
