You get what you pay for! Passes the "look test". It has a clean, well set up screen and scrolling graph. But why do they use the front camera (selfie) for getting their data. The rear (main) camera could get data by aiming at the source without you in the way. It would also be better if you could adjust the graph timeline and have it output to somewhere. But for a free app it is good.

This is one of the least user friendly apps I have ever tried to use. There are no instructions for us, guides, or hints of any type. You open the app and get a screen with nothing but a gauge and a settings button. Does this measure light in real time? Does it snapshot at an interval? It is almost as if the dev's expect you to be psychic or have extensive experience with light meters in order to use this. There is no indication of whether a peripheral device is needed to operate the app.

this app does do what it claims it will, but I was actually searching for something that was a bit more automated. to explain a bit more, I am considered totally blind, having only limited light perception. this app like I said will announce light levels accurately, but I just wish that when the light level changed it would automatically relay that information dynamically to the Google TalkBack service.
