LuxTest: Study Light Meter app analytics for September 13

Study Light Meter helps parents, students, and everyday users quickly check whether a homework desk or reading spot is bright enough for reading, writing, and study. You can use it to: - Check estimated lux for a desk or reading area - See simple desk light levels such as Too Dim, Usable, Good for Reading, and Check Glare - Compare the left, center, and right sides of a desk with a 3-point scan - Save local history with average, minimum, and maximum values - Export records only when you choose to share them On iPhone, the app uses camera exposure settings to estimate desk light. Camera permission is used only for this light estimate. The app does not save photos or videos, and it does not upload image content. Study Light Meter is local-first, requires no account, and is intended for everyday home reference. It is not a professional lux meter, medical device, or eye health diagnosis tool.
