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.

Love it, quick and easy

Nice slick app. Appears to be working real well and I’m getting consistent readings with multiple scans.

Not calibrated to my real light meter

There are some nice features here by the readings are close to half the readings on my real meter
The front camera and back camera are widely different. The back camera is much closer to real lux readings than the camera that faces you or the front camera
Like to see a Calibration feature

This app is a scam. As you are using the free app a window pops up while holding the light read button. Where you thumb is the ‘yes’ to purchase button appears forcing you to buy the full version. No warnings. No conformation. Very shady
