App

It’s an app

Only free for 3 days

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.

Непонятный интерфейс

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

No way to switch to light meter

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.

Difficult and confusing

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.
