Currently, we focus on smartphones, tablets, and mobile devices. However, many of our screen tests work on any display, including laptop screens and monitors.
While sellers using our tools show they care about transparency, always verify test results yourself. Screenshots can be edited, so it's best to run tests in person or immediately upon receiving a device.
