Fantastic app

As a photographer I enjoy this app very much, it’s great to have the look and feel of film in a camera app.

Best light meter app for film shooters

It has everything you need and more, I cannot recommend this app enough to anyone who shoots film!

Useful companion for film shooting

I started looking for a basic light meter app, but when I found out what this app could do it quickly made itself indispensable.

I originally had a Rollei 35s with a broken meter, and this app provided two very useful things: 1) proper exposure settings and 2) a rangefinder to help nail focus for wider apertures with a zone focusing camera.

I now use it with a SLR, and the ability to swap lenses is a nice touch.

It helps me track what I shot on film as well, by saving images and being able to go back to them for proper date and geotagging.

The only issues I’ve had so far are: Every once in a while the metering gets stuck and doesn’t update properly. Closing the app and restarting solves that. The other issue is that the camera control changes exposure compensation, and I wish there was a way you could turn that feature off. I’ve had a few shots where I had accidentally changed the exposure without realizing it because the button is very easy to trigger.

In all, it’s a great app, especially once you learn how to use it!

Needs refinement.

The app has many useful features but, after months of use, I haven’t figured out the interface—too many choices, not enough clarity.
