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.
