About Gadget Tests

Gadget Tests is a set of free tests for the gadgets you use every day: screens, speakers, headphones, microphones and webcams. Each test runs in your browser, and each page explains what your result means and what to do about it, because a test that just shows a colour or plays a tone leaves the important question unanswered.

How we keep it free

Gadget Tests is supported by ads, which appear below the tests, never inside them. Some pages also mention our iPhone apps that do the same job on your phone.

Your privacy

The tests run entirely on your device. Camera and microphone data never leave your browser. See the privacy policy for details.

Who we are

Gadget Tests is made by Wikivec Inc., a Delaware company. Get in touch on the contact page.
