Comments on F Numbers for Android

★★☆☆☆ Alex Rodriguez · Jun 5, 2026

For some reason the app refreshes after making a selection and repopulates the default information... Constant fighting just to make a selection. I have tried to uninstall and reinstall the app but the same problem arises. I would like for C-spec to fix this bug.
