Shielding Tester is designed for quick testing of shielding boxes, cases, bags, and other devices that block radio signals based on the Faraday cage principle. The application measures signal strengths across a range of mobile communication standards, including GSM/2G/3G/4G/5G, Wi-Fi 2.4/5 GHz, and Bluetooth. It provides insights on how effectively these devices block radio signals across various frequencies, assisting in the verification of the performance of Faraday cage devices and accessories. ‣ Test the effectiveness of your Faraday cage within a minute; ‣ Get test results on cellular, Wi-Fi, and Bluetooth frequencies; ‣ Sign in to unlock access to advanced features. FARADAY CAGE ASSESSMENT Determine the effectiveness of your signal-blocking gear! - Open the app. - Initiate the test. - Place your phone inside the Faraday enclosure. - Listen for the sound indication of test completion. - Receive information on your shielding sleeve, box, or bag's efficiency. PERSONAL DASHBOARD Access your account to explore extra features! Store your test results and forward them via email. SHOP In case your Faraday cage underperforms and permits signal leakage, you have the convenience to acquire a tested and guaranteed shielding solution directly from the app. DISCLAIMER On iOS 11 and later, the measurement approach used by the app may exhibit a potential deviation of ±5 dBm. Please be aware that the results provided are approximations, intended to offer a general idea of signal levels and shielding performance, rather than exact measurements.

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.
