### 1/5 — The app does not perform its functions.

*2026-02-24, version 4.0*

First: it’s unclear where the data comes from — whether it’s calculated from the entire image or taken from a specific point.

After testing, I realized it uses data from the whole image. But here’s the issue: the app reads the data only after the camera processes the image and adjusts the exposure. As a result, it always shows roughly the same values.

The app should read the data before any image processing in order to provide at least somewhat accurate information.

When you quickly bring a flashlight close to the camera, the app shows 1500–2000 lux. Then the camera adapts to the brightness, and the readings drop back to around 900–1000.

As a brightness meter, it does not work. Do not buy it.

### 1/5 — Doesn’t work

*2025-08-11*

Doesn’t work on 12 pro max. No screen or camera protectors on either.

### 4/5 — Good app But I have to...

*2025-07-04, version 4.0*

Hi Dev,

I have to comment here as I like this app i just purchased. UI is smooth. 

And Yet, I saw a comment here saying front camera is needed and you said that’s absurd. Hence why I am writing comment here: 
I also think front camera is super crucial, here's why.

My work environment has different lighting settings, some are directly on my head, so front camera can come to rescue. I hope you might see the needs of users, sometimes its hard to comprehend user's perspective (Ik cuz I’m a dev myself too)
Hope my review gives you insight.

Anyway, it's a good app. I so hope you can combine your bundle into one app. Say its "Lux Meter Pro"😂

Thanks from HK user

### 1/5 — Não funciona corretamente no iphone15pro

*2025-03-12*

Os resultados são totalmente diferentes dos resultados capturados no Digital Lux Meter calibrado.

### 1/5 — 完全不准👎

*2025-01-14*

家里的可变亮度智能灯，不论哪个亮度下，使用镜头对准灯光后，app读出的数值都在900-1100之间来回大幅度跳动。完全没有参考价值。

### 1/5 — It’s a toy

*2024-12-06*

It does not change when the lighting changes

### 1/5 — Horribly False Readings

*2024-03-03*

Apparently the Lux in My bedroom at night looking at a light bulb is the same as looking at he sun!!! And generally it always hovers around 1000 but moves in the right direction when the light changes, but it in no way reflects any real measurement at all. Fraudulent claims of the developer

### 1/5 — Disappointed

*2024-01-02*

I bought the combined package of Lux Meter and Kelvin meter. The Lux Meter unfortunately is not working. No matter how bright is the light max it displays  about 900-1000 lumen. I even deleted and reloaded but still no improvement. The Kevin meter seems to be ok.

### 5/5 — Loving it!

*2023-11-01*

I have been using this app for a few weeks to gauge levels of lighting and I have to say it does a great job.  My next task is to compare the results against a calibrated light meter to see how close this is.  

I have the the impression it is going to be fairly accurate.  I like the companion app that tells me the temperature of light as well. Very handy for video and photography to match color.

### 1/5 — Gotta be better apps out there

*2023-07-10*

I never really saw any value to this app. It didn’t seem to matter whether the reading was on top of the table in direct view of the light source or under the table almost completely blocked from the light source, the readings were identical. I provided feedback to the developer about a year ago or so and haven’t heard any suggestions as to what the problem might be. I apologize for the 1 rating, zero was not available.
