By Joseph, 25 January, 2016 Forum iOS and iPadOS Hi all, It's Joseph here. When using KNFB Reader, I have trouble telling when the entire document I'm trying to snap a picture of is visible aside from constantly checking the field of view report. Is there a good way to do this? Thanks!

It would be good if there was a allarm or sound when the app saw the whole page. Agree with apple I agree. either that or a constant vibration thing.
