Lux Meter (Light Meter) Customer Insights

1. No tab to tap on to measure the light levels, no instructions, settings are useless, senseless bothering floating warning,,, about a chart !!?? I can see heaps of comments like this, clearly they are falling in deaf ears.

2. For those who think it is using the wrong side of the phone to measure, you need to look up the difference between incident and reflected light meters.

3. 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.

4. 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.One of the best lux meter you can find on the store.

5. In fact is worth 5 stars as it is but I fell that is missing something.It's tough to know how accurate it is because I have no way to check it, but the numbers agree with my intuitions when I'm checking for high/med/low light levels for my indoor houseplants.

6. But for a free app it is good.I checked its accuracy against an industry standard luxmeter (Gigahertz Optic) and my phone was within 4% of these values except for near zero lux values where it was within 25% but I'm not worried about that, few would sweat over 1 lux difference at 3 lux! Would be nice to change the graph time or export/save/hold measurements.

7. I don't understand though why these light metering apps all measure from the front of the phone.

8. It does have a calibration factor that can be adjusted to match a calibrated light meter.

9. When using a light meter you naturally aim the phone towards the light like taking a picture.

10. It would be nice if it has a lumen calculation because people try to use these kind of apps to measure the luminance without spending a fortune for a dedicated lumen meter.

11. Reflected measures the light after is is reflected off an object.You get what you pay for! Passes the "look test".
