Ratings and Reviews
App doesn’t work. Keeps asking to allow camera access but no way to do that.
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.
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!
With Family Sharing set up, up to six family members can use this app.
