Abbyy TextGrabber 6 for iOS
If Memos isn’t your thing, I’d point out that TextGrabber 6 is a terrific OCR utility for iOS. A friend posted a recipe to Slack and it was a pain to grab the text on iOS. So I took a screenshot on my iPhone and opened the photo in TextGrabber. A second later I had the recipe as plain text ready to paste into my recipe manager.
