Customer Reviews

No customer service. Indoors vs outdoors odd. No color temperature.

Do not expect customer service to ever answer any questions or emails.

Light levels are absolute levels of brightness. Therefore, it's very odd that there is an indoor/outdoor button to set. The two settings get very different readings. Why? It should not matter whether the reading is indoors or outdoors. The number is simply a function of how bright it is.

Other apps on the App Store will also tell you what the color temperature of the light is. That can be very useful in knowing whether it's bluish or yellow-ish. This app does not give you that.


Disregard any negative comments! From an app developer standpoint I appreciate the effort put into this app. For reading light values from a camera, this is very accurate. Buying this app you have to know that it's coming from an iPhone, not a comercial light meter! Great job!

Not accurate

Bought this app thinking it would be nice to not have to carry a commercial light meter with me on project sites. However, when I put it side by side with a commercial light meter (LX 1330B) the readings were not even close to each other. The app readings were less than half those reported by a professional meter and were less responsive to changes in levels when in continuous read mode. I will be deleting the app.
