OCR is Very Good, but to Use it is EXTRA HIDDEN FEE
The OCR is very good, but to Copy, Share, or use the OCR text in any way is an EXTRA HIDDEN FEE of $4.99 NOT described in the apps description at all, not even in the In-App Purchase section.
Furthermore, if in Airplane mode, OCR still works well, but you get no warning about NOT being able to Copy, Share, or use OCR text in any way without paying an extra $4.99 fee first.
