## Most critical reviews (4 lowest-rated)

### 1/5 — Instructions would be nice

*2024-03-12*

The lack of documentation and instructions are detrimental to the proper use of this app.

### 5/5 — Great for natural light

*2025-12-14*

This free and easy meter matches other meters well for natural light. Fancier meters include an artificial light setting; the artificial setting increases the reading by about 13% vs the natural light setting when measuring artificial light.

### 5/5 — Simple and accurate

*2024-04-11*

I've compared this little app with some other, more "professional" light meter apps and honestly it works just as well. The key, as noted in the notification pop up, is to put a blank piece of white copy paper over the camera lens.

### 5/5 — Light perfect
