About

Studying, working, late-night screens—the wrong light tires your eyes first. EasyLight uses your iPhone camera to estimate ambient illuminance (lux) and color temperature (kelvin), then shows clear guidance on whether your space suits near work. It can also nudge you when it’s too dark or you’ve been focusing up close for too long. WHY DOWNLOAD • Instant check: aim at a wall or desk, hold steady for a few seconds • Two-axis guidance: brightness + color temperature together • Eye-care prompts for very dark rooms, dim light, and long near-work sessions • Free to try: daily sessions before you decide on Pro • Pro: flicker observation and everyday reference estimates WHO IT’S FOR Students, desk workers, night owls, anyone who wants healthier lighting habits at home or in the office. HOW TO USE 1. Allow Camera access 2. Start monitoring; point at a wall or desk (diffuse surfaces work best) 3. Read lux / kelvin and the guidance color 4. Upgrade to Pro when you want flicker tools IMPORTANT Readings are on-device estimates for personal, everyday reference only. EasyLight is not a medical device, not a clinical diagnostic tool, and not a metrology-certified instrument. Do not use results for medical decisions, workplace compliance, engineering acceptance, or safety certification. See in-app Measurement & Disclaimer for details.
