StudyLight: Study Light Meter

Light meter for study rooms. StudyLight turns your phone into a lux meter built for one job: checking whether your child's desk actually has enough light to work in — and telling you what to change if it doesn't. Is the room too dim for homework? Is the light too blue for the evening? Is your child sitting too close to the page? StudyLight measures four things — room brightness in lux, light colour temperature, reading distance, and how much daylight the day offers — and turns them into one Study Environment Score out of 100. HOW IT WORKS Point your phone at the desk. Eight seconds later you have a score, a plain-language verdict, and the single most useful fix. No extra hardware, no light meter to buy, no guesswork. Thresholds are calibrated to your child's age, because a nine-year-old and a sixteen-year-old don't need the same desk light. WHAT YOU MEASURE - Room brightness (lux) — is there enough light on the page? - Light colour (CCT) — cool light for daytime focus, warmer in the evening - Reading distance — how close your child sits to book or screen - Daylight — how much natural light the day offers, and how much they get FREE, NO ACCOUNT NEEDED - 2 scans a day with the full Study Environment Score and verdict - How many of the four factors need attention - All 10 study tools — scientific calculator, formula reference, flashcards, unit converter, periodic table, grade calculator, essay outline, grammar reference, scribble pad and Cornell notes - The whole Learn library — articles, quiz bank, light science - 20-20-20 eye-break timer for long study sessions - Light challenges, daily science bite, streaks and today's UV index STUDYLIGHT PRO - Every reading in full, with the exact fix for each factor - Reading distance in centimetres and the bulb spec to buy - Session monitoring — live alerts if the light drops mid-study - Focus scenes that build while your child works - 90-day history, trends, progress and CSV export - Study Companion — planner, timetable, tasks, exams and attendance - Unlimited scans and unlimited challenge plays WHO IT'S FOR Parents setting up a homework corner.
