Lux & Flicker Meter vs AiCoin.com

Light Meter Assistant is a utility app that turns your phone into a light environment tester. Whether you're choosing a desk lamp for your child, evaluating workstation lighting, or checking whether your screen or bedside lamp is emitting proper light, just open the app, point it at the light source, and get a readable light environment report in seconds. 【Core Detection Capabilities】 Flicker Detection: Captures brightness variations at high speed via the camera, performs spectrum analysis, and outputs flicker index, modulation depth, dominant frequency, and light environment risk level, revealing invisible light fluctuations to the naked eye. Illuminance Estimation: Estimates the ambient illuminance range based on scene brightness, telling you whether the current light is suitable for reading, working, or nighttime relaxation. Color Temperature Estimation: Identifies warm, neutral, or cool light tendencies to help you choose fixtures that better fit the scene. Comprehensive Light Environment Score: Combines flicker, illuminance, and color temperature metrics to give a holistic score from 0 to 100 along with actionable suggestions. 【Data Management & Tracking】 History records are automatically grouped by date, with support for tagging different light sources (desk lamp, living room ceiling light, bedroom night light, etc.) for easy categorization. Data dashboard aggregates the last 30 days of test data, presenting score trend curves, risk level distribution, and flicker index distribution for an intuitive view of light environment changes. Light source environment profiles build individual trend charts for each tag, enabling long-term tracking of the same lamp's performance. One‑tap export of PDF reports and CSV data for archiving, sharing, or discussion with family and friends. 【Thoughtful Details】 Smart eye care reminders: Customize rest intervals and daily reminder times to help you build healthy resting habits. Multi‑language support: Simplified Chinese, Traditional Chinese, English. Theme modes: Day, Night, and Follow System – freely switch among three appearances.
