Comments on Shielding Tester for Android

★★★★★ SkepticSeptic · Mar 11, 2025
Works as advertised, tested without anything, then in a microwave, and finally in a Mission Darkness faraday bag and results were as expected.
★★★★★ Russell King · May 9, 2025
Car keys can be used remotely to steal your car. Faraday bags have a metal mesh layer that blocks radio waves. But do they work? I tested 20 I'd got from Hal fords & Amazon and the answer is: from Amazon only one worked. The Hal fords bags failed after 6 months. Even a tiny hole, or even damage to the fibers through wear & tear allows Wi-Fi, cellular and Bluetooth data to leak. This app (free version) allows 30 tests per month. It is the best tool to test and the results are clear. Recommended
★☆☆☆☆ Countess Lovelace · Sep 24, 2023
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.
★☆☆☆☆ D A · Jan 29, 2024
I can't believe this app doesn't make it easier to set the required permissions. It doesn't even say what permissions are required!
★☆☆☆☆ Jerry · Aug 22, 2024
This application does not work! I rebooted my phone, and it still got the same error. " Error 500 The server detected an internal error. (Database error) I was using T MOBILE 5G full bars.
★☆☆☆☆ Baker Boy · Sep 3, 2023
Always gave a false test, even wrapped in 6 layers of alternating heavy duty aluminum foil and cardboard.

Description by Velter KZ Written by the developer, not by AppBrain. Click to read.
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.

Recent changes:
• 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.
