Yo this app is tuff 🥶🥶🔥🔥

This is a very helpful app for film photography.

Reliable easy simple

I can always count on this app. I don’t use anything else except for maybe my meter when I actually have a battery always comes in clutch.

Great app

Has helped with my journey into film photography

Great App

Can’t fault it really for a phone based light-meter.
Pretty accurate and great that you can set up for such a range of cameras editing individually.

It’s saved so many of my photos

I thought I’d be able to just use the sunny 16 rule but I couldn’t so I got this app. It’s very intuitive and incredibly accurate!
