## About LightScreen

LightScreen is a free browser tool that fills any monitor, laptop, or phone with a color at adjustable brightness. Use it as a screen flashlight, reading or ambient light, red light for stargazing, or Zoom ring light. Modes include breathing, RGB cycle, traffic-light blink, and ring light. A screen test shows solid colors for dead pixels and backlight bleed. Fullscreen utilities include a digital clock, Linux terminal simulator, QR code, and harmless fake call or update screens. Nothing is insta

## The Problem

People often need a quick, portable light source for reading, photography, video calls, or monitor calibration, but traditional solutions require hardware, apps, or installations. Existing flashlight or ring‑light apps are platform‑specific, and monitor testing tools are separate utilities. Users also want an easy way to create ambient lighting without extra equipment.

## The Solution

LightScreen runs entirely in the web browser, turning any display into a fullscreen light source with selectable colors, brightness control, and breathing animation. It doubles as a monitor test tool (white, black, primary colors) and a virtual ring light for photography or video calls. The service is instant, cross‑platform, and requires no downloads, making it a lightweight, free SaaS utility.

## Who is it for?

Desktop and mobile users who need a quick flashlight, reading light, or mood lighting; photographers and content creators seeking a virtual ring light; developers and designers testing monitor uniformity; stargazers needing red light; anyone looking for a simple, no‑install screen lighting solution.
