OCR tools comes very handy when we are working with a lot of text that are saved as images. As with any other OCR tools, IMG to Text App is a free iOS app that converts image to text. I have used this app very frequently and I can say that it works incredibly well. I was working on a restaurant website when the client gave me their long menu pages. I was able to scan all the text without any hesitance. Off-course you may need to use inbuilt cropping tool on your iOS device for better results.
