I used this app on my android phone to meter a roll of Ektar 100 and LomoChrome Purple on my Bronica SQ-Ai recently, i metered the shadows and they all turned out exposed great.
I'm guessing if you are spot metering you have a decent understanding of what light metering is and how you like a scene exposed?
I use this app in the same way, i generally know how i like my shadows exposed in film, so i use the app to meter those shadows and expose based on that. I do much the same if i'm using a camera with built in metering, look at the shadows and meter based on that.
I recently metered two rolls (ektar 100 and lomo purple) with this app and they turned out exactly how i wanted. So long as you know how to meter a scene i think any app would work though.
> Unfortunately I only metered with my digital
Why unfortunately? I metered my last couple of rolls with a phone app and they turned how i wanted.
