About

Point your camera at a spot and instantly find out if it is bright enough. Light Meter reads the light level (lux) and gives you a one-second verdict — enough / a bit dim / too little — so you get the answer even if the lux number means nothing to you. ■ Great for - Finding the right spot so your houseplants get enough light - Checking that your desk or study area is not too dim - Seeing if a bedroom is dark enough for a good night's sleep - Judging whether there is enough light to shoot a photo ■ Features - Camera reading with a big judgment icon and a one-line verdict - 5 use-case presets: plants / reading & study / bedroom / desk work / photo - The bedroom preset is reversed — darker is better, and it warns when too bright - Open, aim, get the answer. One screen, one purpose, no manual - Fully on-device. No AI, no server upload, images are never saved or sent ■ Free / Remove ads (one-time purchase) All presets and verdicts are free to use, with a small banner ad. A one-time "Remove ads" purchase hides every ad. It is not a subscription. Note: readings are camera-based estimates meant as a rough guide and do not match a calibrated lux meter. This app does not guarantee any medical, health or plant-growth effect, and is not a substitute for occupational, school or other regulated illuminance measurement (which requires a JIS C 1609 / standards-compliant meter).
