Exactly what I need, nothing more

This app is simple for me to understand and I love that I can see both the average metering and the spot metering at the same time. Other apps I tried had so many buttons or sections that I could fumble around and miss a shot. This app never lets me down. I’ve entered my camera + the film stocks I have and it’s so easy to choose the film and get going. 💪

The best of the best and so accurate!

I am a professional photographer and Director of photography working on both coasts, so as you can imagine, I am constantly in need of a check for exposure in between shots and set ups, and although I do have my trusty spectra, pro light meter, being able to check and double check, my readings with this app makes my life much much easier!

If you’re wondering whether this is worth the subscription price, then I ask you aren’t you are perfectly exposed shots virtually priceless???

[and on a sidenote, the customer service they provide, for their subscribers is impeccable!]

A ++++.

I found this app through Reddit and I’m so impressed!! I can’t afford a nice light meter and this app has never failed me. Super easy to use. At this point I don’t even think I’ll buy a light meter! Can’t recommend this app highly enough
