## What is Light Meter?

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).
