### 2/5 — Has a weird lowest-light-condition cap

*2026-07-22, version 3.1*

In very dark situations (night time long exposure photography, for example) the meter stops measuring under what’s the equivalent of iso 400, f11, 8 seconds. In situations that require 60 second exposure for iso400, f11, it still gives 8 seconds.
 Could have been great, but unusable for my purpose because of this cap.

### 3/5 — App

*2026-06-10, version 3.1*

It’s an app

### 1/5 — Only free for 3 days

*2026-02-17, version 3.1*

Only 3 days are free. Then you pay monthly or annually. I don’t like it when this isn’t transparent before downloading. Feels manipulative. I’d be more likely to buy if the developer was honest from the get-go.

### 3/5 — Непонятный интерфейс

*2026-01-25*

Как выйти из режима экспонометра ? Чтобы вернуться обратно в люксометр приходится переустанавливать приложение.

### 1/5 — No way to switch to light meter

*2025-12-30, version 3.1*

It switched from Light Metre to some kind of professional photography interface, and there is no way to switch it back. It says double tap, but it just doesn’t work.

### 1/5 — 全然ダメ

*2025-12-14*

有料にしても、お遊びレベル以下。実用レベルではない

### 1/5 — つかません

*2025-12-09*

開いたらカメラ設定画面で黒画面になります。
全く使えません。
使用を確かめようにも使えません。

### 1/5 — Difficult and confusing

*2025-11-18, version 3.1*

I wanted just a light meter / measuring app. It started out fine, but then I clicked something accidentally and got into photo mode. Could not get out; still can’t. It said to “double tap” to exit, but that hasn’t worked. Tried changing the settings and it’s just advertising the ways to pay - but I have. Don’t pay money for this app - find something else that actually works.

### 1/5 — Difficult

*2025-10-23, version 3.1*

Difficult lemon

### 2/5 — Already Paid but still free version

*2025-10-17, version 3.1*

I already paid the subscription but it still on free version and ask me to subscribe everytime I wanted to change premium setting
