Best of many free light meter apps tried. Ads are a bit more intrusive (fullscreen at startup) than with some alternative apps (small banner). But layout is superior in many ways: showing mean & median values since reset as well as both lux & foot candles all readable at a glance. My Samsung reads similarly to a calibrated meter under some conditions, but is mostly useful only for relative comparisons not absolute measurements. Still very useful.

it's ok but for some reason it measures a new data point only when the lux changes, not over a set unit of time. This makes it difficult to compare to active change in light over time.

I like the app, it may not be perfect but it uses your phones internal sensors to do what it says. Easy to use and understand.

Works perfectly although I've never tested it next to a calibrated lux meter, app has few ads.

does what it needs to, reading will only be as accurate as your light meter is.

"This app is compatible with you device." No, it isn't. Samsung SM-G386W doesn't have a light sensor.
