Light Meter is an easy-to-use, functional light intensity (lux) meter perfect for measuring, comparing, and adjusting lighting levels in your environment, whether at work or at home.

Using multiple device sensor inputs, this small, convenient app collects light intensity data at the click of a button. It is indispensable when using a manual or film camera, without the need for expensive instruments that often cost hundreds of dollars. Great for setting up your greenhouse light settings, avoiding workplace lighting induced eye strain, or checking if your desk or craft station needs a bit more light.

Looks good, but unfortunately the advertising banner in this Free version goes right over the words of the icon at the bottom; so can’t see what is meant to be what.

This is the most ridiculous oversight I’ve ever seen in a free app. I understand advertising banners being in free apps, not a problem, but to be in the way of functionality, stupid and I would of expected the developer to have tested it first.
I’m deleting it now as it has no function.

Works fine

Saw earlier poor reviews regarding banner issues so I’m commenting to say it works fine on my iPhone 7 Plus.
I needed this to get a rough idea of lux levels and it does exactly that.

Does nothing

Sounds good. One minor jiggle for this light meter is that it doesn’t actually measure light levels. Permanently on zero. But so close to 5 stars...
