Pretty good, but note the limitations
I was trying to scan some old bulletins (typewritten, so pretty standard font). What I wanted was a searchable PDF file of the bulletin.
This product will not help me with that.
The OCR was OK. If the text was prose, then it did a good job. It fell down when the type was not perfectly clear, and when ALL CAPS were used (which the editor used often for peoples names).
Also the bulletins tended to have little pictures spread across the page. That tripped it up, and they were converted to random gibberish characters.
My rating would have been higher, and I would find the app useful if it could mail the entire PDF when I was done, with the error-filled text, so that I could correct it offline. The description says it, but Ill be clear -- when you send a "image" PDF, your only option is to send an image of the last page. Nothing else. Not the first, nor all, just the last.
If you send the _text_ as PDF, it can be multi-page, but I didnt catch that subtlety before purchasing.
