### 5/5 — This one works properly and works for me !

*2026-02-06, version 1.0.12*

It’s very accurate and great for film photography. Especially when vintage film camera light meters are suspect, wrong or simply no longer work.  The exposure value triangle is very easy to interact with in this app. You can take spot light-meter readings from any part of the “viewfinder” / “picture”.  Brilliant app that works properly. 😀

### 5/5 — Один из лучших экспонометров для пленки

*2025-08-25, version 1.0.12*

Всего три ползунка, кнопки на фронтальную и основную камеру, запоминает значения если выйти из приложения. Просто идеально, ничего лишнего. Зачение выдержки/диафрагмы получаешь в два клика, очень удобно и не отвлекает тебя от съемки.

### 5/5 — One of the best

*2025-01-11, version 1.0.12*

1 small issue is the size of the text, sometimes I adjust aperture when I want to adjust SS.

### 5/5 — Clean & Accurate

*2024-11-23*

This is my favorite light meter app, by far. An extremely simple and easy way to get accurate metering quickly, and it looks great too. A bit of a learning curve (it’s extremely minimalist) but brilliant once you get the hang of it.

### 5/5 — Выдающееся приложение!

*2024-10-21, version 1.0.12*

Наглядность, простота и функциональность на высоте! УСуперудобно, что можно в кадре нажатием на экран посматривать экспозицию. Это дает возможность легко выбрать экспозицию как по-светам, так и по-теням или задать значения эксповилки.

### 5/5 — Clear and Simple

*2024-09-26*

Thanks Luis for giving us this super easy light meter app at no charge. Love it!

### 5/5 — Amazing app with perfect exposure metering

*2024-09-10*

I use Lightmate all the time with my Mint RF70. Every photo that I’ve used the metering results from Lightmate have come out stellar. If time permits, I never take a photo without it. Highly recommended. Will definitely be using this with my incoming Rollei as well.

### 3/5 — Odd values

*2024-07-29, version 1.0.12*

As a photographer I’ve never had asa/iso 560 film or 140. I want 500 but it’s not there. 

Also shutter speeds 1/12s, 1/6s 1/45 etc ???
Still it works and although a bit clumsy to use - the values change too quickly as you slide your finger and can’t be locked. 
No option for whole scene average reading only where you tap on the image.

### 5/5 — To Luis

*2024-07-25*

The community appreciates you! Thanks for making this app free for us out there who can’t afford a light meter

### 4/5 — Put some space in between the S,A,I!

*2024-07-18, version 1.0.12*

Put some space in between the S,A,I! It’s so close to each other
