Frequently asked questions
How do I open a full white screen?+
Select Open full screen. On iPhone, our touch-friendly fallback fills the browser when native fullscreen is unavailable.
Can this help me find dead pixels?+
Yes. Dead or dim pixels are easier to see on a uniform white background.
Can I use it as a reading light?+
It works as a temporary soft light. Lower your device brightness if the screen feels uncomfortable.
Does the page collect screen data?+
