The app seems to work ok, giving exposure time estimates based on light meter reading, ISO, and aperture. Custom apertures are possible, f/222 for example, which is critical for pinhole photographers. Unfortunately this app is ad-supported, which is neither disclosed in the description nor shown in the app screenshots. So thanks for wasting my time...
Great,but...

I love this app! My only problem is if you zero out the f-stop the app crashes when you go to change it again.
Loved it until....

This is a great app. When it works. When trying to change f-stops, the app to crashes. The only work around I've been able to find is uninstalling and reinstalling.
Excellent App

Works great, gives accurate readings across many light spectrums. Ad-based, but they aren't too intrusive
Excellent!

This app works great for 3D printed pinhole cameras, and the only thing I would like to see is a selection for films at ISO 125 & 320. Other than that, keep up the great work!
