The Shielding Tester helps quickly test shielding cases, boxes, and other Faraday Cage devices. It measures GSM/2G/3G/4G, Wi-Fi 2.4/5 GHz and Bluetooth signal strength, showing how well the device blocks radio signals (in dBm). There are two testing modes: a detailed mode for in-depth analysis and a quick mode for fast checks. After each test, you get a report that you can save or send to the manufacturer.
A must-have tool for anyone developing Faraday Cage-based products—shielding cases, bags, anechoic chambers, and even mobile shielding structures.

• Added Ping Device — a new test that works without an internet connection. The app connects directly to another device via Wi-Fi and exchanges data. It can be used for offline testing of signal shielding, connection stability, and packet loss.
• Updated the design — the app is now even easier and more convenient to use.
• Fixed minor bugs and issues.
