About this app

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.

Wi-Fi Bluetooth and cell phone testing work great but I cannot register and sign up for an account. Tried with Google and another email. Screen just froze.*update: customer service reached out and gave me a login. The spacing is finicky on the login but it's working now. Ty!

Tested a microwave and an ammo box. Wireless, Bluetooth and cell signals were tested. All showed varying amounts of shielding. This is the best app I've tried out of several with easy-to-follow graphics.

Didn't work for me. I needed to test all individual devices and needed to know which devices were emitting signals. This software requires the cell phone to be put into the bag. Very inconvenient and would be preferable if it was detected from the outside.

Hello dear user, Our app is designed to test shielding effectiveness by placing the phone inside the shielding device, not to detect external emissions. We'd appreciate reconsidering your review. For more help: hello@velter.co
