FAQ
Do I need to install anything?
No. Everything runs in the browser; some tests need mic, webcam or screen-share permission.
Are results accurate?
The basic versions give relative checks; for frequency curves, channel/phase and THD, use the matching Pro membership tools.
Is my data uploaded?
Testing is local; audio/video is never uploaded — used only for live analysis.
Does it work on mobile?
Most tests support mobile browsers, though some (gamepad, full-screen dead-pixel) are better on desktop.
Is it free?
Basic tests are free; Pro versions are membership features with precise measurement and report export.
