### 5/5 — Ease of use

*2026-08-15, version 4.0.5*

A great app to use with any vintage camera that doesn’t have a built in light meter. I use it to occasionally check my Sunny 16 rule, when it’s not exactly bright and sunny.

### 5/5 — Accurate and easy to use

*2026-07-11, version 4.0.5*

I have gotten back into film photography and have been testing many old cameras. Most of the time the original light meters don’t work, and rather than buy a random cold shoe unit I use this app. It’s works great. Very accurate and versatile. I’ve developed photos that are very well exposed in camera.

### 5/5 — All you need

*2026-06-27, version 4.0.5*

A simple, clear light meter app. Not for complicated situations, but does everything a simple, straightforward photography light meter needs to do.

### 5/5 — Great simple product!

*2026-06-27, version 4.0.5*

Love that it just works. Has everything you need in it.
