I just downloaded Scannable, primarily to scan business cards and save them to my contacts. The scan and OCR works pretty well, but when I click on the card, then click on "Save Contact", it typically doesn't work. I have to tap multiple times for it to work, if it ever works at all. I even have trouble clicking on the X in the upper left corner to exit the scanned data. I am using an iPad mini4 with iOS 11.2.5. I am using Scannable to scan cards to update my contacts, so I can bring them into Cloze for Contact Management. To bad I can't find a decently priced system to do everything in one package.
